Short version: DEVONthink needs top and bottom margin space in full screen mode.
Long version: I didn’t know how much this bugged me until I tried out WriteRoom and it felt so nice. The top margin isn’t so important, but the bottom is critical. On my Powerbook, once the text fills the screen, I am typing along the bottom row only, and my fingers obstruct my view. I am, essentially, typing blind. Which makes the full screen view, for me, only usable for less than one screenfull of text.
Give me some ten or twenty pixels at the bottom where no text can appear (in full screen mode) and this feature would go from being only semi-useful to my full-on-favorite way to write.
Unless, someone already has a workaround?
