I have a few suggestions.
One:Admin Requests.
Works just like the Trust, only for admin. Yes, ignore is enabled. There is also a Kick/Ban button.
Useful for finding admin askers and banning them, or a quick way to grant and ask for admin.
Two:OnLook event
When the center of the crosshair points at an object, something happens.
Useful for things like an eye scanner or a bot red light-green light.
Three:Raycast laser and OnRaycastHit
A special emitter that fires a raycast. When the player hits it, it activates a variable on the firing brick.
Useful for things like agent movies with invisible lasers that appear when you throw things into them.
Four:Ice Bricks
A special brick that makes the player slide when on it.
Useful for things like ice skating rinks or ice hockey minigames.
Five:Special Controls
A special Host-Only GUI that can do things like kill players, respawn them, look from ANY brick, see a minimap of the game; complete with players, and more.
Six:Player prevention GUI
A special Host-Only function that allows them to "protect" players from kicking, banning, killing, or brick destruction. Can also prevent players from doing those, or "lock" the server by autokicking everyone but the host, setting players to one, and changing the server name to (LOCKED).
Useful for about everything...
