As a creator who already pays for a large community region, sometimes I want to dip for a while and have some private space to build.
It's not economic to pay for another full region to be up all the time. Mainland homes and Premium homes are nice but too small for creating and have neighbors. Similarly, sandbox regions lack privacy.
I'd like to be able to spin up a region that only exists for as long as I'm in it and pay only for that usage rather than have it be on all the time and the associated costs.
Ideally, some way to backup the rezzed contents of the region would be present, so I can pick up where I left off. Better yet make a region save state an inventory asset so I can switch between different environments quickly.
