I would enjoy a different admin system in a new version of Blockland. Maybe not V11 but later on.
SubAdmin - A person who can kick or ban for 12 hours. Can have Destruct wand and clear builds. Can F8, fetch, find.
Admin - Can kick and ban players and SubAdmins up to 7 days. Can clear bricks has Destruct wand and can change the map. Can F8, fetch, find and load bricks.
Host - Can do whatever s/he want to do.
Another thing I would request would be if you want to save the bricks from the server that can be a option to save all bricks or just yours. If you pick all bricks. It would send a request to a Admin, that they would accept or deny.
