ok, I have another suggestion, some file managers (like free commander and xplorer2) let users to access drive list in panes. by this approach users can do anything they want by contest menu key in panes. these file managers lag behind MC in some aspects, but this feature is so useful for people who don't want use mouse for some basic operations. in these file managers Ctrl+Back Space lead users to parent directory of current drive in each panes, another Back Space lead users to my computer where they can see their drives. without this feature people must use mouse and right click on drive icons on toolbar or go to windows explorer for some simple operation like formatting drives, checking usb drives for virus, ejecting usb, etc. attached pic shows this feature in free commander
sorry for my english
