Feature Fixes and Returns, Edition 1 (12/31/22)

Oh boy I've been wanting to write this problem I've had ever since Musescore 4 came out.

I've had only 2 problems with features in regards to the new reorganization of things in the first edition of Musescore 4. To get the important question out of the way I'm using Windows to run Musescore.

Mixer:
I like the display that the devs for the software put in for the new mixer, however, back in the final editions of Musescore 3, there was a menu within the old mixer that allows me to change the instrument voice from, without the need of using the "change instrument" button from the palettes (Ex. Bass Guitar would be my part but I change it to sound like a distortion guitar to "add" distortion on my part). What happened to that menu in M4? If it hasn't been removed in M4, then what do I need to do to change the voice from within my part?

Guitar Palette:
The new guitar palette is really handy for when I'm writing riffs or transposing music by ear so I can learn guitar the problem with this new palette and M4 is that whenever I'm using distortion guitar after putting the "distort" bar from the master palette, if I add a palm mute (P.M.--|) , the sound goes to a clean guitar palm mute instead of a distorted palm mute. Sure I can add in a staccato into the notes, but I want to hear a distorted mute instead of a clean one whenever I add distortion to my instrument part. Is there a way for the "distort" bar to override the palm mute system from switching to a clean sound into a distorted one? If not then this guitar palette will also be a pain in my rear to use whenever I'm writing.

Guitar Harmonics:
This more of an idea than it is a request for a fix, so this point could be on the wrong forum.
Is there any way for the devs to add guitar harmonics to Musescore? Tapped (T.H.), Artificial (A.H.), Natural (N.H., written with "<" and ">" marks around the fretboard number), and Pinched (P.H.) harmonics in the software would be an amazing feature for guitarists/bassists to utilize when writing parts. To give an example of an artificial harmonic, if I were to play a G4 on guitar or bass and tap my finger on the 19th fret, the sound that would come out would be a D6. What I'm suggesting is to have a menu to adjust the pitch of an artificial harmonic based on a certain note and adding bars like the Palm Mute bar (P.M.--|) to tapped and pinch harmonics (Ex. T.H.--|, and P.H.--|), except for the natural harmonics, which was explained earlier.

Happy New Year's Eve/Day from wherever you read this post :)
