Feature request: Envelope curves editing (tension points)

[Javi Grex 4]

Hi!

It would be nice if the curves (track envelopes, clip envelopes, fade in and fade out) had a middle point to ease manage the tension of the curve. 

Now, we have to select (using right click) between 3 predefined: linear, slow curve, fast curve, jump (only for track/clip envelopes) which it's quite limited and slow.

Here, a serum vst example image, showing this tensions points:

Here a gif showing and example in LFOTool vst plugin

Thanks!
