Is your feature request related to a problem? Please describe.
Sometimes I forget which icon is which, f.ex a buff or a spell cd when setting up the order inside an meta icon.
Right clicking or going into the dropdown gives the information, though sometimes it's a bit tedious.

Describe the solution you'd like
Not a big thing, but would be a small QoL if this could also be reflected in the tooltips on the icons in the row themselves.

Describe alternatives you've considered
Make sure my hidden groups have a good setup from the start, or just go into the dropdown menu but it's not always easy to remember, for instance if icon 18 is supposed to be above icon 20 etc.

Additional context

Great idea - will be in the next release!
