Feature request — Expanded or expandable - Envelope Widget with more control points

Build a TG77 preset (shared now) There are 13+ controllable params per FM operator’s envelope and I hit two limits in dx7envelope.

  1. Control point count. The DX7 envelope widget supports 8 control points. The TG77 operator envelope has 15 total parameters (the 8 the widget covers, plus 7 more: HT, L0, RL1, RR1, RR2, PEG Sw, SLP) — 7 more than the widget provides.

  2. Knob assignment. The widget supports 1 knob per control. All 8 points can be edited, but only 1 can be assigned to a knob. Editing the other 7 requires 7 separate controls elsewhere on the page.

Request: An expandable envelope widget that supports more than 8 control points, with a knob assignable to each one.
