Settings is a feature that allows you to mint TIME while sending the acquired TIME to another address. This is useful for additional privacy, or for minting multiple TIME while the current mints are still vesting. Note that if the same account holds multiple mints, the pending rewards from the earlier mints have to be forfeited.
Note: What this means in practice, is that if a user has vested rewards from a previous minting action purchase, and he then mints another TIME, the 5 days timer is resetted for all the rewards, and the vesting period will start again.
