When one selects View > Select Groups Column and the Keyboard Maestro application responds, I've noticed that the Select Groups Column menu item is no longer enabled (i.e., it is dim).
This seems logical.
In comparison, however, when one selects View > Select Macros Column and the Keyboard Maestro application responds, the Select Macros Column continues to be enabled.
@peternlewis is there a purpose for this difference?
