This is a simple plasmoid that sits on your panel and, on click, simply displays the file contents of a configurable folder in a drag-scrollable "drawer".
Scratches the itch of the default folderview plasmoid NOT being sanely operate-able with a touch screen.
Might be kinda rough around the edges. I might or might not work on it further :)
