I think that this kind of drop-down menu should be changed.
I think in the current 2.93 build it’s used only in the Add Object Tool, but I can see it used in other tools of experimental builds, like the soc knife branch or the soc curve branch.
I get that this entry was chosen maybe because some menus have a range of options that are not focused on something, but honestly this is a poor choice from a UI perspective and from an “informational” perspective, it literally doesn’t convey or explain anything of what the menu is about, plus not being aesthetically pleasing.
In the specific case of the Add object Tool, it could be renamed to “Placement”, for any other menu/tool it should be named after what the options inside are about.
