An Android client would indeed be easier to use, but would also take much too long to develop (not talking about iOS, I do not have any Apple related skill), so it's very unlikely to happen.

One easier solution (perhaps something I'll do at some point) would be to have a smarthpone specific interface. It's true that the current interface is not really tailord for small screens as I had tablets in mind when designing Ubooquity, not smartphones, which I never really considered a suitable reading device (although I know a lot of people do).

Closer to us, the next version of Ubooquity (1.7.0) will add OPDS support for books and comics, allowing you to use any OPDS client (Android or iOS) to browse your collection. Not as good as a real native client but it should make browsing easier.

The target date is mid-december, stay tuned !
For folder covers, Ubooquity is supposed to take the cover of the first comic book found in the folder or one of its subfolders.
Files and folders are sorted by path. But there is a bug in the current version (that I identified thanks to your message) which makes Ubooquity use the last folder instead of the first.
It is now fixed and will be part of thenext version.
I have no plan to add more advanced cover art features though.
Java is supposed to be able to manage all charset, so the problem should not come from your locale.
I have not been able to reproduce this problem (at least on Windows): I have a lot of comics whose names contains accents, and they all work fine.
Could you check in your log file if there are some errors when Ubooquity tries to import the files ? (if you want, just send me the log file and I'll take a look).
And could you tell me which operating system you use (Windows, Linux, OS X...) ?
This is not a bug, just a missing feature.
The "Minimize to tray" option just removes Ubooquity from the taskbar when it is minimized, it does not automatically minimize the window at startup.

But it's not a difficult feature to add, I'll do it.
Hi,
could you tell me which browser you use, on which platform ? (Windows, Linux, Mac OS...)
Better yet, if you could take a screenshot of the problem.

My guess is that this is the placeholder the browser displays when it has not received the image yet. Does it stay or is the image displayed only when waiting for the comic page to be loaded ?
