Posibility to enter envelope-values by number (textbox)

[TonKazanKezan]

I think it's cool live let users scale up their trackview that easy to have a wider or narower range for the envelope-values.
But sometimes, like the master tempto-envelope, I just want to jump or move to a strict value, like going from 135 to 140 BPM.
It would be nice to have some contextmenu on a rightclick of a envelopehandle to set it to a exact value (type value in a textbox).
That would speed up editing a lot I think!
