Plugin.

Why does it exist? It's useless as well as ugly.
If anything, things should be change to display something similar as shown on the right.

It's neater, you get the same information, and you don't get that ugly ass line as shown on the far left.

It's fine, not such a big deal tbh

I dislike it.
Sometimes I just put my mouse over someone's username and that thing pops up, and I've to click somewhere else to make it go.
