Hi,
I'd really like to have a function in the ressource manager to remove all items from the active file that are not currently in use. Like, I load a bunch of symbols (e.g. tables) to see how they look in my scene, then I choose one. All the other tables still float around in my ressource manager window of my active file. So now I'd like to have a button (or a menu entry, or...) to remove those from the active document.
