control-click on multi account containers (MAC) is simple. "hide" just works.
but there is no symmetry to "unhide" or "show" -it is nothing like as simple and clear.
I think some UX here could improve this to make it much more 'one click' and essentially symmetric: the method you use to hide a container, is a toggle and the same method shows hidden containers if selected the right way (I appreciate this means a > menu to select from many)
