Is it possible to apply a corner radius to only a specific edge on floating menu items?
I'd like to make a strip of buttons in a floating menu that looks like one object (which I do quite often with Touch Bar buttons) by setting buttons side by side (no spacing) with 0 corner radius, but I need the left and rightmost edges of the outer two buttons to be rounded to resemble a single button's appearance. It doesn't seem that this is an option currently in menu item configuration.
My current solution for the end caps of this strip are blank buttons with negative margins so they appear rounded on only one side, but of course this isn't ideal.
