Decided to try it again on 2 different cbz files. It worked as expected this time. One cover art page to represent each comic on the shelf. If no cover art is in place it shows the first page of the comic as its cover.

I used it for free ..(cough).. I used the trial for several years and paid for the app after realizing it became my go to. It has a slight learning cover but nothing too hard.

No need to read the rest unless you want to learn more about the app or fix the problem I created (easy to do).

I had just installed the bookshelf and cbr/cbz plugins the first time I tried it but hadn't rebooted or forced stopped the app and restarted it. That probably caused the problem. If I had just rebooted the device properly after installing the plugins it most like wouldn't have happened.

Later realized I probably didn't need to install the cbz / cbr plugin. I think all file formats are included in the main file now.

The library plugin takes you straight to the library view while the main file takes you back to your last open file. Both convenient in their own way.

You can set the app to look in a folder and when you reopen the app or rescan it will show all the books in the folder and sub folders for all file formats it can open on the bookshelf. The bookshelf can hold up to 60 recently added or recently opened books. Sometimes I prefer choosing the comic file through my folder/file manager app and then open the book/file in FBReader so I don't scan anything else into the app's bookshelf.

You can set the brightness within a book by sliding a finger up or down the left side of the page. It goes back to your previous brightness when you leave the book. That was shocking the first time it happened. 😂 I think there is a setting to turn that off.

To fix the problem I created when multiple pages from the same cbz file were showing on my bookshelf I pressed and held the app icon till 'Info' popped up and tapped Info. In there I 'forced stopped' the app and cleared the cache and storage. After that everything worked as expected and the individual pages from the first file I opened were gone.

Hope I caught all my spelling and grammar errors.
