Link current frame between scenes I am new to blender scripting. so, If I have two scenes open, one being the master scene with VSE only, and other scene with animation. Is there a way to link their play-heads so that if I move current frame on VSE, it moves on animation scene as well ?

This important for in-context changes during animation, when multiple scenes are composited. I have been trying to replicate functionality of After Effects in Blender.

Or is there a better way to do this?
Was given the solution by @batFINGER, in another post. 

add driver to Scene.current_frame?

by using app handlers.
