Duplicate tree #5291
Description
Detailed Description
In the tree tab, hovering over the tree-specific menu, could show a "Duplicate Tree" (or even "Duplicate Group") entry which simply duplicates the tree.
Context
Copying a tree as a lightweight, implicit backup can be handy when mutating it. After the mutation, it's also handy to be able to compare before vs. after (without having to go through version control).
