There is one thing that drives me crazy when working on a large site that I didn't build and that is that there are a bunch of blocks in the block list, one called 'events_calender' for example. I can't delete it so I know it's not a custom block. But I can't find it in the module code anywhere, so eventually I realize that it's a view. It would be helpful if there was a note next to each block saying what the source is, whether module or view. If this is an intelligent suggestion, let me know and I could suggest it. If it's not, let me know that too. :) Thanks.
