What mod adds this feature

[Nori]

So, I have probably too many mods and one of them adds a button that is a picture of a helicopter. Clicking on it brings up flight operations and the settings gear has hover control setup. I have no idea what mod adds this.

Anyone know?

That comes with any of @Angel-125's WBI mods.

Took a while, but found it, it's Kerbal Actuators (which is a dependency of numerous other mods)
