(I was a bit unresponsive lately. Sorry about that. The situation will probably be like this for some time more.)

FBReader (http://only.mawhrin.net/fbreader/) is now at version 0.7.2. Changes:
Added bzip2 archives support.
Added screen rotation by 90, 180 and 270 degrees (all versions except of Qtopia).
Added Esperanto hyphenation patterns.
Added TCR file format support.
Minor bug fixes.

Wow! Rotated text!

I know lefthanders have been asking for this, but on the RocketBook, I used to read for a while holding it in my left hand, then rotate the text -- and physically rotate the device so the paging keys were on the right -- and hold it with my right hand.

So I imagine I'll get use out of this too.

I've only seen one other program for the Nokia 770 that rotated the display, a game that hasn't actually ever made it to release.

Nice work!
