I was thinking this same thing.
I run charity tournaments, and I add a paying position for every additional 10th player, (past 30); as this happens quite often, I'd like to be able to expand the payouts without stopping the clock, or rushing during a break.
Also, in busy tournaments, it would be handy to have more than one admin system; allowing more "cashiers" to check people in.
Additional admins would also allow for supervisors to remove players and handle re-buys (as opposed to re-entries) and add-ons at the tables.
Some one else's suggestion of a pin for additional admin's seemed a good idea.
Thanks for a what seems a great app, I'm anxious to test it!
