Google analytics just insists that people are searching for “grid leader icon.”
The only plugin I found that will show a “leader” (party or raid) was GridStatusParty. It will show different color boxes for party leader, raid leader, raid assistant, and master looter. However, it will NOT show icons. Not combined with another addon, not if you ask it nicely. No icons.
Yeah, I wish I had better news. Honestly, I’m kinda perplexed why so many people want this feature. When you’re mid-healing, meh, who cares who the raid leader or master looter is. You can always open the raid interface and find that out.
Anything else you want to know how to do in Grid?
