Either you or me are confused about between MUI (Amiga/MorphOS) and the other MUI.

There is no TreeView in "our" MUI but for sure in the other one.

Then you talk about editing menus in the post you linked too.



There is ListTree in MUI as used in Panel prefspane, and it can for sure be edited on the fly just like you can build a context menu right when the user does clicks RMB.

Edith:
Embedding buttons in List(Tree)Views is possible, but not trivial.
Also be careful to don't use List(View) methods on ListTree, they might seem to work but will lead to severe issues.
