Hi Andre -
Great plugin overall, but I've run into a small usability problem with it. When you go to edit the order of posts in a particular category, the interface displays posts which are in the trash right alongside posts which aren't. There's no indication what are trashed posts and what aren't. This is causing some confusion with my end users.
I'd suggest either not displaying trashed posts, or if you do want to display them for some reason, give them a different style—grayed out or something to that effect. Perhaps set up an option to switch between the two possibilities.
