authorized user idea

I keep running into this issue as many other do.
I share a plot with a friend, I put a 2nd store/crafting table etc, etc, so I can have a friend use it to add stuff, use calories to queue up stuff, etc. But since I'm not the plot owner, I can't authorize them.

can you add another section to authorized users,

Manager Users+ (allowed to add or remove other users from "Authorized Users" section)

Authorized Users+ (current system used)

just a interesting idea for "Authorized Users". drop box timer, (infinite, 1,3,6,12, 24 hours) so after set time, the user is removed from the list.
