Please let me address your questions/requests 🙂
– To add a new point in the path, you can do so by right click an existing point and selecting “Add Point After” or “Add Point Before”.
– Unfortunately no, the F (focus) does not work for path points selected (at least now).
– If you mean for the point tangent handles (the circles), then yes, I can add xyz gizmos to those as well 🙂
– I could add an option to look ahead in the “Animate On Path” clip, but in this case isn’t it better to use the existing “Follow Path” clip which does this already? 🙂
– I’ve just added an option to choose the “up vector” in FollowPath clip and attached it for you here.
– I will need to really look into this request in detail first to provide an answer for whether or not it is possible 🙂
