Well, today's budgeting was a bit late - didn't wake up early this morning - and I found myself so disgusted by the prospect of maintaining two budget spreadsheets that I just figured out a good workflow and finished my local one. It's entirely caught up. I retroactively know the exact dollar and cent amounts in my accounts on August 1st. I figured out date formatting so it would include the short weekday. I can focus on one account at a time and entirely transcribe history. All of this is going to pay off for incremental updates, too.
I'm still figuring out how best to do future projected expenses, but I have some ideas. Will pursue next.
