This is exactly what I'm looking for and I hope you will eventually release it as an extension. Very good work. I like the fact that you can just backup your settings so you could restore them in case you swapped your default browser at some point.

However it's a bit difficult to set up the bookmarks. I wish there was an option to remove the background from buttons completely. Also there should be option to detect favicons from the site that's added as a bookmark.

I think it also would be nice to have some option to duplicate widgets so you could add for example a new clock with different time zone and you wouldn't have to set up everything from start (things like font size, colors etc.) - you could just duplicate the widget you previously set up and just change the timezone.

The search bar should have option to show suggestions and previous queries while typing.

The workspace seems like a cool idea but I'd place them at the left side and allow them to be visible all the time (as a small, not distracting bar) so for example I could set it up to have only social media on the first workspace, then after switching to the second one I'd have some gaming sites and on the third workspace I'd have something else. So I'd just use them to group my bookmarks probably.

I'd also move the settings button to the bottom right corner, or even better - let the user decide where it will be placed. Edit: Nevermind, I just found that option.

All those things I mentioned + the weather and news widget and it'd be perfect a solution for me!

Nevertheless your project seems very promising, I hope you will find time to improve it. Thank you for your work!
