Connector lines should work between frames as well

Yes! Why I want this is that this enables me to point to a ‘bunch’ of content, contained within the frame, where (a) that content organisation persists when I move the container, automatically, but (b)  is also flexible within the container.    

This is something I only get by using a frame. 

Using e.g. a shape as a container for other content doesn’t work because i have to manually group it and ungroup it and group it etc. etc when I change the container content, so that I can move the container around and have it carry all its stuff with it.
