when I set up my macOS 12 beta for testing last week I was invited by Apple to install a feedback app on the system. I happily agreed and have since put findings about minor glitches in the beta into feedback items. A very simple idea but the data flow will have to be curated which I suppose is really time consuming on Apples side.
I know that XOJO also has a feedback app for developers to share findings with a) XOJO Inc. and b) the community - this in my opinion is an even better approach.
