Menubar and Plugin Icon Placement Question

A recent post on Footprints with Cutouts got me looking at making another plugin to move Footprint Dwg items to Edge_Cuts (vid below).

Plugin is finished and I now have around 20 plugins and at the point of dialing-down to 14 of the most useful ones.

The problem is, the Icons consume too much space in the Menubar, thus extending the Window’s width too much. Yes, I could make smaller Icons but, smaller is too small.

I did make a pop-up panel with them but I prefer keeping them in the menubar.

Question: Where and/or How to tweak which level in the Menubar to place them and/or set Menubar size ??

I’ve searched and searched but find nothing useful…
