Great stuff, thanks Ingo!
I've got a site that has a few hundred pieces of data that need to be updated but must not be deletable. Previously I've used a CTF for this since it allows for permissions to be set for actions like edit, add etc. There may already be a solution I'm not aware of...
Also: is there a way to have the full table appear on page load (as if you pressed search with no filters selected)? I don't think we got an answer to that one, but I'm a little food-deprived right now, so excuse me if we did! ;)
