I've had flairs half-implemented on the back burner for a while now, but never merged it in since I wasn't sure if other front-ends were doing it similarly. Will probably go ahead and finish that since at least one other UI will handle them the same way.
Found this feature while trying to figure out why post title is created at such an unexpected place. This is nice. Now if people start actually using it.
I've noticed it quite a lot actually, for posts tagged as "meta", "oc", "discussion", "rant", etc. the most useful I've seen is in !comics@lemmy.world, because people mark the posts with the comic creator.
