More options for (node) context menu

[philippotto]

The following can be implemented:

• (un)mark node as branchpoint Added shorthand to mark branch points from context menu #6012
• drag node (is this still necessary when we have smart drag?)
• ...

@philippotto Both ideas mentioned here are implemented. I am in favor of closing this rather unspecific issue and (re-)-open issues for specific ideas or upgrade this to issue to an epic collecting more ideas.

Yes, I think, this issue can be closed, as we already iterated quite a bit on the context menu and now that the branchpoint part is also covered, there is not much value in this issue.
