- we should be able to 'move' instead of copy items, using drag and drop and a modifier key.
- exclude empty strings from query, probably multiple occurances too.
- fix the editable table header cells.
- can't drag and drop to an empty stack. (I think this is a GNUstep-gui limitation)
- Scripting support doesn't work with the new gorm based menus.
- when pasting cards into a stack, we should highlight them, once they are placed.
- copy/drag operations work, and paste/drop should be altered, to function like "Add Card".
