I'm sure this has been suggested, but at the same time I haven't been able to find the suggestion by searching, so here it is.
The only reason anyone would ever want to obliterate anything would be to reduce the database size. So, the obliterate list should show the size of each item in the list and the list should be sortable by size, so we can clearly see what's taking up the most space and obliterate it.
Thanks.
