It took me a while to understand how to use the Spending Plan, but I've come to really like it. I find it presents a simpler and more useful way to budget for the month.
One suggestion would be to add recurring transfers in addition to "Bills & Subscriptions" as a category that is deducted from Spendable Income.
Currently, I have several recurring monthly transfers that operate more like savings (e.g., mortgage principle, brokerage, 529s). Because I transfer the same amount every month, I don't consider this part of spendable income. I can account for them in my Spending Plan by including them in "Bills & Subscriptions," but they're not really bills. It would be great if I could separate them from the recurring bills in my Spending Plan.
(Of course, this probably requires working through some bugs with recurring transfers, which I know is an ongoing issue.)
Anyway, the Spending Plan is great!
