[Feature Request] tracking total (combined) amount over time

[ChaosNicro]

Heya,
Sushi is wonderful for keeping tabs when you pay for other people. I usually use a debit transaction to clear a paid tab, bringing it to zero but keeping the history. I recently had to proof/audit a tab, and it was difficult to track the total (debit-credit) over time.

Maybe the details of a transaction could show the wallet's total at that point in time, or an insight graph that tracks total amount?

Thank you for providing this app.
