It’s easy to mistakenly activate an element on the wrong level - for instance finding oneself editing a menu wrapper instead of a menu trigger, or more often all the way back to the section.

Just one false click . . .

I may simply be too new at the application to have discovered an available method but I’d like the means to keep work focused on the level it needs to be at.

This greatly added to confusion while learning to create a drop down menu.

So my question or suggestion is have a control feature in the tree that would effectively lock layers above a selected level.
