Feature request: Budgeting not based on account balance

I don’t know if this is available or requested before, but perhaps it is worth creating a budgeting based on the total budget itself instead of the account balance?

If I have £5000 in my account, it doesn’t mean I want to spend all £5000 of it?

It’s also that some current accounts have much better interest rates than savings, and so it’s much difficult to track?

Currently all of my category budgets (groceries, travel etc) are entered as figures, e.g. £500, and not as a percentage of the total balances.
My monthly budget is then sum of these budgets (+ any recurring transaction outside of these budgets) [or at least I think that is how it is used].

Perhaps log a request with CS if you need more help
