I don’t know if it was after some big patch or something, but I suddenly realized there’s a number under the calendar icon by my minimap.
Mouseover labels it “AddOns”.
However, I can’t figure out what it’s supposed to be counting. I have far more addons than that number has ever depicted. If I left-click on it, a list of that number of addons appears. But I don’t know why that set is selected. There seems to be nothing they have in common other than I do, indeed, have those addons installed.
Does anyone know what this is supposed to be?
