Addon search / request

[Qhival]

My wife just started playing, and I had no idea skills were locked & hidden now until you do specific things to unlock them. It really confused her.

Is there an addon that adds these locked skills to the skills window, perhaps greyed out and with a tooltip that explains how to unlock each skill? If not, I would like to request one. I posted a comment on harvens improved skills window, but it's been years since I was active, So I don't know if he is active anymore.
