When I open Snap in Safari (this doesn't happen in Chrome) I cannot use CMD anymore to cycle through all the open macOS windows.
What have you tried that didn't work?
CMD+Tab/ShiftTab doesn't allow me to move to the next/previous open window in macOS.
I like a lot having shortcut combinations in Snap. So, can I disable Snap intercepting just specific combinations? Or can CMD be (optionally?) moved to CTRL in macOS?
Oh yes! How did you think they got so rich? They make a point of how virtuous they are because they don't directly sell your info to other companies; they just use it to target advertising to you that they predict you'll click on. But they have the information, and (sometimes) they respond to police subpoenas.
I think we do the best we can, given what the browser tells us.
It's funny, you'd have thought a priori that Safari, written specifically for MacOS, would do the best job of keeping command and control separate. But no.
