First add-on is the enlightenment tracker: it should show how long each of your vet chars require to be logged off until they recieve enlightenment. Nothing more is really even needed for this add-on.
The second add-on might be a bit more difficult. But essentially would make guards healthbars not only show up, but show more prodominantly than any other healthbar in the game. What I mean by this is that instead of the regular healthbar over their head, it could display the gold boss healthbar over thier head like how it looks when you highlight them.
Thank you to any modder who takes up this challenge. I eagerly await seeing either or both of these soon.
