Hi, is it possible, in the Folder Tree pane, to hide the file system and show only the Favorites?
It's not. You could do something vaguely similar with a vertical toolbar that listed your favourites, I suppose.
I have tried this:
Preferences -> Folder Tree -> Start Folder Tree at: Current Drive [which should reduce the vertical space for the file system object]
Preferences -> Folder Tree -> Show in Folder Tree: Favorites
However, when opening a Lister (e.g. at startup) the actual Current Drive tree is expanded and the Favorites tree is collapsed. It should be exactly the opposite!
