I have one suggestions for new maps. When i played samp all maps were uploaded to the server, but not all were into the vote rotation. So only admins could start those maps and then could decide to put them to the rotation or delete them.
I don't know if its possible, but it would be cool if this happenns, because we have time to test the maps and to decide if a map is good or not.
Maybe those maps can be marked red in admin panel or in the F4 panel, so we know which map is untested and not in the rotation yet.
