Hidea, the "font" directory in your archive is empty. Is it intentional ?

Scrollbars already appear automatically when the description is too long, but the comic details window is allowed to have a height of up to 900 pixels until they do.

Having a better usability on small screens (especially mobile ones) is something I plan to do. I don"t know exactly when though.
In the meantime you can try the user created themes (see the "theme" section on Ubooquity website), perhaps they will behave better on small screens.

Sure !
Done.

Ouch, I made a mistake saving this field as an integer whereas the ComicInfo XSD allowed any string of characters.
The bad news is, a fix will require a full rescan for everybody when it is released.
I have to think about it.

Thanks for pointing it out anyway.

The best I can provide is this script.
You can also try to follow the links in the FAQ where people explain how they managed to install Ubooquity on different devices.

Not a problem. :)

Your ideas are interesting as they would not require that much work on my side. ;)
(as long as you write the text file or provide the images)

I'll think about it.
