Thanks for the suggestions, Yam. We have had other suggestions for different layouts--vertical rather than horizontal, tabs, etc. For now we're focusing on our core layout (some of these other layouts pose some problems for actions like drag and drop, not to mention the multiplication of time it would take to implement new features in multiple layouts), but we haven't ruled anything out in the (perhaps slightly distant) future.

We do have font size manipulation coming out very soon, however--it's implemented in the development version already.

The note window I find to be very useful when working with long pdf documents. My main suggestion would be to allow the notes window to stay on top all the time. Winamp has this function and it works great.

My second suggestion for the note function, which might be harder to manage, is if I copy a selection from a pdf file, to have the page number automatically attached to the copied text. This would mean I wouldn't have to lift a finger to actually type the page number in. I try to separate my physical work from my mental work.
