I've seen a couple of addons in Youtube videos that look useful and I can't identify. A virtual cookie to anyone who can help me out please

Firstly:

This looks like an Enemy thing but I can't find any options in Enemy to show the Enemy career icons above their heads. It also doesn't seem to show them for all enemies in the video so it may be doing something slightly different that I'm not getting. It would be useful to be able to identify careers at a glance though.
And secondly:

What's the addon that pops up showing which effect is snaring/rooting/disabling/etc you? I tend to get tunnel vision at times and a popup like this might help with that

Thanks very much
