This idea is more of an anti griefing idea rather than a creative addition. Essentially, adding a Set Marker Limits option allows hosts to put a restriction on how big of an area creative commands can be used. For example, you could set the size of a usable area to 32x32x32, or simply a diameter of 32. This would ultimately force griefers to take longer in order to delete work, but still allowing players to use the Creative permission.
"But Trub," you might be thinking, "Why would I give someone untrustworthy the ability to use markers to begin with?"
Well, constructive criticizer, many people enjoy opening up maps where they let people build freely. These players greatly benefit when given the Creative permission, as it allows access to shops at the push of a button! It also lets them use markers to speed up building time.
So instead of having to: a) make sure a player is trustworthy with creative commands, OR b) watch over players like a hawk, hosts can limit how large of an area markers are capable of deleting and filling.
If you have any C&C for this idea, please respond. If the only thing you have to say is "+1," just leave a like on the OP. Thanks for reading.
