I find the Savings insight very confusing to look at because it is not clear where the balance on the graph is coming from. It seems to ignore the actual balance in the account, and the change over time does not accurately reflect reality because it ignores transfers between my checking and savings that are marked hidden by default. I also notice that when switching between 6 month and 12 month views on the graph, the balances actually differ by thousands of dollars, even on the same months! This graph is essentially useless to me.
I would like to see a savings insight that simply looks at the total balance in my savings account at the end of each month and the current month and shows that over time. I'd imagine that's really what people are trying to glean from this view in the first place...
