I totally hear you, there’s lot of value on this and one of the reasons why we designed it. We took the idea from Fantastical so it’s a proven pattern that we know serves the purpose very well.
The part I think we’ve missed is to make the representation of the balance perform as an actionable piece of information. We had solutions for all the problems (removing outliers and one-off purchases, for example) but the actual implementation of those things is quite tricky and, as a product, we’ve prioritised covering more surface (delivering new features, etc.) over polishing previous elements.
That leaves the Pulse in a hard place so that’s why it will probably make sense to move into something easier to build, maybe not that theoretically powerful but more sustainable with the cadence of delivery we’re aiming for. In essence, it’s better to have a modest but nicely build and functional house than just the blueprints and the foundation of an amazing mansion.
