Envelope progress does not show delay period

Progress through the amplitude envelope is shown by a moving dot which is really cool but this does not show until the envelope starts its attack. If this is delayed then there is no indication during this delay period. It would be good to see the dot start as soon as a key is pressed and move along the bottom towards the attack curve.

I see this in the full application on Windows 10.

Yes, I noticed this behaviour.
There is also no env delay reading or ability to set ENV delay to note values or milliseconds as with the LFOs.
