Accessibility comes from setting notification settings right and turning on the volume (I’ve missed a few by putting headset aside, need to turn it off first).

Meetings, either I am an active participant or it’s a background noise.

As for the file explorer / sheets etc, yeah I alt tab. I wouldn’t be able to keep all the stuff on the screen anyway now that I need Xcode VScode Claude-cli Emacs & few terminal windows. If I’m alttabbing that, alttab to Finder or Browser isn’t much harder.
