It would be nice if Charts had the capability to do basic performance calculations such a Take-Off/Landing Distances, Fuel Burn, Cruise Speed based on power, GS calculations, etc… Particularly for common GA planes (e.g. C172S, PA28, SR20, etc). I know the same thing can be done on Simbrief, but having it directly in Charts would be a little handier; like an on-the-fly performance calculator rather than a full-blown OFP and flight briefing.
Foreflight has that function in their higher tier subscription, and Fltplan GO has that feature for free. One can have the “curated” profiles by those developers, or make their own performance profiles from scratch.
