I suggestion I mentioned in the other thread (I believe) is to the option to have additional info . In vertical mode to the right of and in portrait mode under the file name. This info could either be the date or the size.

In addition how about when typing having it "quick-filter" like the regular file manager. So you could type and it will only show the files that match what you type. Similar also to fapman when typing in the package list.

Last, why not steal a page from the firefox design?
* Have the top bar (up | home | location) be part of the scroll area of the file list, so when you scroll down, to goes up as well (like firefox's location bar) meaning you will be able to see more files on screen.
* Have the buttons on the right be 'invisible' unless you drag/scroll the windows to the left to show them. This can be achieved by having the button in the same scroll area as the file list and making the list the size of the screen so the buttons will be offscreen unless scroll-en to.

Great app! Thanks!
