Request: Add timeline states or proberties to data model

[mrtnRitter]

In my usecase, there is a startup animation, in which LEDs should have a given color.
After this startup phase, LED color is driven by fan rpm.

In the data binding editor, there is no node to read out timeline state (start, main, end) or other timeline proberties (Transform Position, Scale, ... )

Would be a good feature to add, to give more flexibility and control to the user.
