A suggestion, if I may:  Make the automatic payment feature payout the whole balance.

Currently, if I hit my threshold of say 3 BTC around noon, I don't get paid until 2300 (which is fine; I don't care about the delay).  But, at that time I only get paid 3 BTC.  This leaves behind a balance of whatever I made between noon and 2300, which complicates determining my hourly or 24-hour earnings.
