"but it's all about opinion and workflow" But it's also about statistics. Only very few people had something negative to say about it.

1) "It's non-jailed. So what? Unless you use two monitors you need to close it to get it out of the way as it's set to always on top."
"So what" - because you never tried to understand benefits or explore, it will remain "So what".
Before 2024 you could not even do anything unless you exit jailed picker window. So to me, this: "to get it out of the way" doesn't make any sense. If you need a shortcut to close it, ALT+F4 should do it. And yes, I use 2 monitors.

2) I think you identified one or two items that require more than one click and that supposedly ruin the feature for you to the point that you reject it.

3) Mine is superfast. No lag at all. Old computer?

4) Not true. There is an option to have a different behavior for demo audition on double click. Could be better, but option is there.

5) "More non-intuitive and far more fiddly than the old picker."
I disagree entirely as no facts were presented. It is very stable and intuitive compared with bouquet of modal pickers that all looked and felt different like they were bolted on at different times for different reasons.. All content in one place now. More unified look. And yes, non modal. I can have it sitting on another screen and use it as needed.
