That "handle" is canvas aware editing, and that is in the works
currently. No small task by any feat, and likely means that one view
will become the reference point as it does with every other compositor
out there.

Typically, the moment you select an active node in most compositors,
the viewer will switch to that node as input for interaction, and the
adjustments can be made in a given active viewer. It just happens that
Blender's viewer has evolved somewhat from an historical point, and
the holistic approach was not possible.

I do like the idea of using a gripper as a driver however, but that
might be another subject.

This has recently been discussed quite a bit on this list.

As with all things around Blender, I find it useful to believe in the
folks that have coded it and realize that there is likely a reason
that the things are the way they are. Sometimes it is historical
legacy code that can take ages to rewrite, or sometimes it is another

With respect,
