Possibly a common problem in mapmakers, I have found that my "maps" directory becomes cluttered. However, I keep my older maps for reference, and have no wish to delete them. I therefore suggest that the editor display maps, not in alphabetical order (CW3) or creation order (now) but by date last modified. This will keep the full list, but make sure that active projects remain in easy reach.
I am guessing that this will be a relatively simple change, but if not, it's not major.
