The ability to change the background color of the entire program? Second, a bug: Q-Dir doesn't always show the creation of a new folder in the folder treeview. I've noticed this especially when I'm extracting a compressed file to a new folder: the folder is created and visible in the listview, but doesn't show up in the treeview, even after pressing F5. The only way I can get the new folder to show up in the treeview is by restarting Q-Dir.
When pointing to ftp folder, it will open a new instance of Windows Explorer Furthermore, i found a error message when i copying large number of file (say 3xxx files) from one Qdir pane to another Qdir within the same instance. I don't know what the error message said since it is not in English. After i press OK (not in English), it still can copy. I remember that I output a very small negative number (I guess is somewhat overflow).
