6. "undo" for magic sheet editing that undoes only the last magic sheet edit

7. unloading a sub from a fader shouldn't stop effects or change levels.

8. Have an option to hide/collapse/resize the parameter tiles. I never use them; I use either encoders or ML controls.  Not relevant now that the "about" display can be in a frame.

9. Enable a rate submaster fader for step-based effects Implemented, thank you

10. When creating a magic sheet - if I select fields to be a certain color, they should be that color from then on and not keep showing up in white.

For #8 if you hold down the [Data] key and then select the parameter tiles in the CIA it will hide those parameters.

i think with #8 he means to get rid of the tiles as such. but wouldn't collapsing the CIA do that?

Yes, it would.

Yes, it would.

If you want your ML controls to open in the CIA, it would be nice if the tiles weren't there to cut down on scrolling.

It would be nicer to some day to have a way to open controls in an ephemeral window, kind of like the way the virtual keyboard on Nomad works, especially for context-sensitive controls like the ML control or certain magic sheets. I think that's what the OP is getting at. The tiles are wasted real estate if you don't use them, and the ML is wasted real estate if no channels with multiple parameters are selected.
