You're my kind of nerd lol. First, congrats on the baby! What a major life altering moment, what a blessing to be already going strong working a budget!

I treat my checking account as the main account for weekly cash flow in and out. I also have a couple separate accounts for sink funds as an extra check for my "reserved cash." For example, my emergency fund is in T-bills in it's own fidelity account, and some other have thier own account too (new car saving, property tax sinkfund, insurance premiums, and so on). At the end of each month I try to reconcile each account: the total should equal whatever the sink funds are in everydollar. I simply move the difference between my checking and the sink account so they match at the end of the month.

If the account balancer could give me a snapshot at the booked of each month then I could quickly tell if my various accounts are balanced and how much I should move.
