[FR] Bring Back the "e" Button for Insert Panels

I like many things about the new mixer, but the blue graphic “bar” for the inserts isn’t necessarily one of them. I feel like we get less info and functionality out of it then from the old graphics.

For one, we need to double-click instead of single-click to open the insert panel (GUI). One solution is that on mouse over the “e” button could come back into view, similar to the way the power button shows up now.

Thanks for listening!
