It would be great to be able to create a smart group using the unread/read status of an entry–this would be, it seems, an easy fix. As it stands, it’s not easy to figure out what needs to be read. It would also be nice to be able to adjust the boldface for unread items–I find it distracting.
A more important thing: the layout is a mess, or at least one’s ability to control it is messy. The little boxes in the lower right corner of the screen are not clear, especially when you can make areas dissappear and reappear by dragging their borders. This it seems needs some rethinking–it’s not very mac-like. I’d like to have a pdf preview below my general list, and the field entry and preview on the right–but this ins’t, alas, possible.
