Andrew, thanks again for your persistence and the work you put into these themes ! Minimalist is now more usable than it's ever been, especially on the N900. I find Light more readable than Dark for long threads with many quotes, but that's a matter of taste I guess.

The only missing item that was on your "done" list is saving vertical space in page headers. The "new posts" page especially shows an almost empty screen in a fullscreen MicroB on a N900. The regular topic page is a bit less drastic but there is still room for improvement (like having Menu and reply on the same line, reducing line spacing etc.)

I will try to add screen caps to illustrate if Minimalist lets me do it from my N900 :-)
