Also, it'd be really nice if F5 refreshed and F3 searched. These are pretty standard Windows buttons. I can live with crtl-f, but F5 REALLY needs to be "refresh". I hit it constantly.
Finally, it'd be really nice if I could attach the directory structure view in the left pane to one of the two folder panes on the right. ie: Whatever directory I switch to in the folder pane the directory pane automatically opens it - like Windows Explorer does. The option to turn this on and off, and attach it to either pane, would be great.
Finally, last thing. When I'm in several directories deep, the title bars of each pane are shortened. It'd be nice if they'd display the entire extended path in a tooltip when I hovered over with the mouse.
Anyhow, I love the software, keep up the good work!
