Does anyone have or willing to construct a PopupActionList?
Scrolling a long list of menuitems can be problematic for users who have trouble holding down mouse button or keep tapping downarrow. So the user sees a scrolling list popup which has scrollbars but stays up until an item is clicked on. Similar how the ActionMenu works.
I think many others would find such a control very useful.
I live on very limited income so can’t pay you; but hope you might consider the challenge to make a useful control object. 
PopupActionList[title, {lbl:>action, etc...}]
