This might be me doing something wrong, but quite often when I double click a folder in the folders list, it opens up an existing folder not in a clear space on the screen but over the top of another folder. Other times it causes the existing folders to scroll upwards and put the new one down below. It’s really annoying and I can’t find an option to stop it doing this. Sometimes when I've had 7 or 8 folders open at a time, they're covering 4 screens or more, which makes it impossible to see what's in most of them.
Ideally I’d like it if v5 would display folders side by side, so I can read what's in each of them without being forced to drag them around the screen all the time.
