This is a thing that might also go in bug reports, but my biggest pet peeve with a lot of programs out there is lack of standard columns when browsing. If you double-click in between columns in the search window, it'll automatically resize it to fit the content. However, the other 2 windows don't seem to do this, which is quite annoying. The other thing isn't as important, but it bugs me when it doesn't show the column header when you're dragging it around. This makes to hard sometimes to estimate how much you're gonna see.
