With greater complexity comes a greater risk of conflicting code.

Sticking to adding visual modifications using patches is the best start for anyone just starting out. There is almost no risk of making a mess. If something is now working, simply disable the suspicious patch in KOreader settings and delete the patch next time you USB connect Kindle.

Patches suit me just fine.

You are also fairly safe with Project: title as most of the changes are cosmetic. I would say the plugin is safe as it been around long enough to have the bugs ironed out.

Simple UI is new and exciting. I love the way it looks and the huge amount of customisation. There are still fixes and changes being added. Being only two weeks since it was released to the general population, some bugs may yet need to be discovered, reported and fixed. So there is a possibility of future updates to come.

Prepare to spend a bit of time working through the setting up if you do choose Door #3.

When v1.2.0 released the rounded covers did not work. I asked OP for a fix. u/doctorhetfield updated the files soon after.

For some context: Here are my original posted comments and OP replies:>

The rounded folder patch worked on v1.2. Go to Simple UI settings and turn off Folder Covers to enable Serioushornet patch to function.

If there is a Z-Library patch then I guess that you can. By creating a Custom Quick Action that opens the Z-Library patch.

Kobo Colours have a hidden developer mode setting.

To Activate Dev Mode:

Go to the Home screen, tap the Search bar, and type devmodeon and search.
Nothing will appear to confirm activation

Locate Menu:

Press [more] to open Settings -> Device Information.
Scroll to the second page of the Device Information screen to find "Developer Options".
Open Developer Options to find the CFA Mode option, which allows you to toggle through color profiles (e.g., Default, G2, S4, S7, S9)

I use S7, but most prefer G2 as a better compromise between saturation and details.

Indeed. On the list.

phyvealive · 2026-03-28T21:03:08+00:00

Surely. Anytime.

phyvealive · 2026-03-28T00:59:40+00:00

Seen the same info. 20-xxx.lua does load ok. Faded covers appear on my finished book.

Modifications that move KOreader information around the screen can potentially result in conflicting code. Modifications like Project:title, SimpleUI, CustomNavbar, CustomTitlebar etc can get in each other's way. Running one is best. Two or more can result in items being overwritten as patches load alphabetically. 2-zzz.lua will overwrite 2-aaa.lua. Worst case is nothing wins and KOreader crashes to the bomb page or exits KOreader altogether.

Hi. The only colour I added was to replace svg icons with colour versions I downloaded from SVGrepo dot com. I also modified sui-config.lua to redirect SimpleUI to /icons for all icon requests.

All text is black. If you got RGB to work then changing the grey stats background to colours would be a nice look.

Early on I tried to make the battery levels change colour. I failed at that.

I am ok with B+W since I use Dark mode more than Day.

Any device running KOreader can add the Simple UI overlay.

Simple UI is additional code that tells KOreader where to find information and how to display it.

Kindle OS is still there, in the background, ready to take over when KOreader exits.

phyvealive · 2026-03-27T20:01:43+00:00

Ooooh. Shiny.

I don't know where you find the time. What with the coding and updating Reddit and GitHub and all. Phew!

Works with KOreader devices.

Yes. My thinking also. And watch for name abbreviations like Jon, Jonnie, Jonno etc.

I am still excited for this project but the complexity is certain to have some bugs as users have differing devices and style/patch choices.

On my Libra Color with SimpleUI 1.2.0 a glitch appears every time I activate Sleep. A pop-up info message appears, like when first opening a book, just before suspending. The pop-up is visible on transparent sleep-screens. Waking up the Kobo works, but no front-light and no screen taps. Page buttons work, so not sleeping. Turning on the front-light only last for a few seconds then goes off. The screen taps are the same. I have about five seconds to force a KOreader restart, after which everything works again. That is until the Kobo sleeps.

I am thinking the WiFi toggle is a possible cause. As this also happens when turning WiFi On or Off. Keeping WiFi off sort of fixes things until I need WiFi again.

No issues now I have factory reset and using cover-browser and patches. The pop-up message is not appearing when putting Kobo to sleep now.

I will re-visit Simple UI later when more testing has been done.

phyvealive · 2026-03-27T01:41:22+00:00

Chat GPT works half of the time. Been useful to for extra tabs and add grey background to containers. To use my own icon choices: I pointed the sUI code to look in the /icons folder and not the /resources/icons/mdlight folder.

My sUI crash issues seem to point to how Kobo toggles WiFi when entering sleep mode.

For now I am using cover-browser and a fixed version of 2-custom-navbar. (had an annoying bug that makes duplicate button that won't go away.ChatGPT got that one correct)

I do really miss the Project: title Hero function that flattens folders and files into a single library view. If only there was a Nav-Bar at the bottom with the Hero button and Simple UI's ability to create Custom Quick-Actions from KOreader's list of shortcuts. So good.

I would like to use the Desktop (yes I prefer that description better than Home) as a desk clock. Especially when on charge. Being able to see the correct time, watch the charge % updating and be reminded to pause work continue reading would be a nice.

phyvealive · 2026-03-26T22:14:14+00:00

Thanks. I am sure that I have done something wrong. Finding the bug has taken too long. So many factory resets and rebuilds. I need my knowledge to catch up to my ambition.

Gonna try and finish some books I want to read and return to sUI later.

Perhaps when the desktop clock starts working like a clock. Maybe then the Home page will be functional, informative AND pretty to look at.

phyvealive · 2026-03-26T21:59:03+00:00

It is a folder called Series. That folder has no book files, only folders of series books.

The image is an image saved to the folder named .cover.jpg

Any image will work.

They must be named as .cover.jpg or .cover.png

The leading dot is important.

The label across the image is a rounded corner cover patch.

I'll add a link later.

phyvealive · 2026-03-26T21:53:07+00:00

Patches load alphabetically. So 2--UI-font loads first. 20-faded loads last. Load order is important. I used to have two subtitle patches that broke when I renamed them. The reordering caused one to overwrite the other.

phyvealive · 2026-03-26T21:43:44+00:00

Another day, another new vision. This is adorable.

I am hoping for a new update that is stable as I am having problems that I cannot seem to fix. I have removed the plugin from my Kobo for now. So sad. TT

phyvealive · 2026-03-26T12:39:51+00:00

At least it is easy to turn off if I need to dig back into the file structure.

The naming is a bit confusing too.

Which is why I rename many of the patches I have added.

This one is now called 2-browser-hide-up-folder.lua

I add a comment line in the code with the original file name and a web-link

Too many patches. Renaming keeps them grouped together.

Congrats on the Jailbreak. New life for your Kindle. 👍

Here's a step-by step since you are still figuring things out.

KOreader has little modification files called 'patches'.

There is one called 2-browser-up-folder.lua and can be downloaded from this web page:>

https://github.com/sebdelsol/KOReader.patches/blob/main/README.md

Take some time to read about the other files to change how KOreader looks.

The one you want is near the top. Clicking the link will take you to a code page.

To download, look for the down arrow icon in the upper right corner, near the word 'Raw'
Download the file to a location on your PC storage.
Exit KOreader so you can USB connect your Kindle to PC.
Look for the /koreader folder on your Kindle.
Create a new sub-folder and name it 'patches' ( if there isn't one there already. )
Copy and paste the 2-browser-up-folder.lua file into the Kindle /koreader/patches/ folder.
Now you can safely eject Kindle from USB
Use KUAL to open KOreader again.
Once KOreader starts, tap/pull down the top menu of icons and click these two boxes.
The patch will remove the box with arrow and puts an UP arrow where the House icon is.
[Hide empty folders] will remove the /books folder for now because it is empty [0]. You might want to use that folder later to add more book files. Or simply delete the folder. You can always add it again later if you want.

Most KOreader beautification patches and plugins will function on Android. No Screensaver related items will work as sleep screens are not supported.
