(or Unify drivers and F-curves)

This separation, Drivers and F-curves, I find artificial and leading to lots of limitations. Basically, drivers are just some F-Curves with an influence/connection to another F-Curve or property.
To date, combining the two needs artificial props in using empty and others and the UI with 2 such separated concepts and 2 separated graph windows is not intuitive.

Switch between a Driven or Keyframed curve is also tedious, so if you change your mind it becomes quite complicated.

Also, inside Graph Editor, F-Curves don't have a way of linking/following/relating to other F-curves (except scripting, of course)

[I can provide examples of how it's done in other software]
