> - The tempo stretching example in the video was too subtle for me. I listened a few times and had trouble telling the difference.

that's the point of it. Being able to make 124 bpm samples cooperate with 110bpm samples without anyone ever noticing that it had happened.

> - The documentation at https://manual.audacityteam.org/index.html is still for 3.3 which is a bit frustrating when trying out new features. Also the link labeled Manual that is displayed in the splash screen 404s for me.

the manual job always takes forever to complete, but support.audacityteam.org is updated.

> - It took a bit too long to scan my computer for plugins and at the end I was told some plugins were deemed incompatible but not why.

It tries to load the relevant VSTs in a child process and if the VST crashes the child process it gets flagged as incompatible. Audio plugins are awful and nobody ever follows the spec.

All of the other things you mentioned are in various stages of being planned.
