1) When I try to delete multiple locked items, there is no indication that the operation didn't work. The confirmation dialog shows up, and appears to work, but doesn't. (You dont get the ("item is locked" message like you get when deleting a single item).

 

2) Would it be possible to make a system field ~itemlocked, that could appear in the grid? If not, what's the easiest workaround to show all my items, as to whether they're locked or not?
