Cascade menu even if clicked on button (but not arrow)?

I dont remember how but I made it work that way before - it was very useful on touch screen (tablet).
After I reinstalled everything I cant find it in settings… Was it removed?

Hello - if the top level button does ot have any command string at all, it will immediately cascade the linked toolbar.

-Pascal

Is it possible to apply this to all cascadable buttons at once? It used to work on all buttons like that.
