Proposed Musescore 4.1.2 update

For example, I want to use the old mixer, but unfortunately I can only use the new one. I hope to update the mixer that can tune unsupported MIDI instruments and other drum sounds (that is, the old Musescore mixer; If you don’t like new mixer, you can switch to the old one at any time; that is, there are two mixer options, for example, the new mixer “Default” and the old mixer “Older”; I hope to put these two options in the middle + above the mixer.), like this I sometimes use it and it's handy, because I reinstalled Musescore 3.6 and found that the installation failed; Or there is a built-in function of transcribing songs, so that I don't need to install additional software for transcribing songs. For example, AnthemScore requires money, and it is no longer available.

There are also suggested App updates
I hope that the score of Musescore 4 can also be loaded into the Musescore moblie app.

Please take a look at this article about unable to open Musescore 3: https://musescore.org/en/node/352877
and this: https://musescore.org/en/node/352413

On July 31, I downloaded the Protable version of Musescore 3.6.2. Although it has not been updated to 4.1.2, I can continue to use the old version, but I don't know when the 3.6.2 version will expire.

I Love Musescore 3.6.2

(I hope that Musescore can update Musescore 4.1.2 to this version on August 5th.)
