Fuel info displayed on Navigraph Charts

Hi,
Occasionally when I’m doing long haul flights, I am a set and forget person. But like to track my flights through Navigraph Charts. With this, I want to suggest adding fuel info to the telemetry bar. Such as, fuel on board, fuel consumed so far, estimated total fuel consumption, fuel efficiency (units per distance), etc.
Others can suggest extra features for this, or tell me this already exists and I am blind.
Thanks!
