Hover Module

I've seen someone ask for a hover button, but I'd like to suggest a whole hover module containing more useful options than could be represented in a single button. Such as:

Hold ASL

Hold true Alt.

(A text box to input the desired altitude for the first two buttons)

(Heading text box for hover direction)

(A velocity text box for hover speed)

I'd code this myself as a script but I don't know how to yet and it seems as though it'd be easier to handle as a plugin.
