Need to work off a laptop more over the next month so I dug the macbook air out. Did my MacOS upgrades, etc, and yeah wow those are some rounded corners yo!
Thank god for AltTab's ability to bring a 'hidden' (cmd-h'ed) window to foreground when cmd-tabbing, unlike the default tab switcher on mac, who's behaviour I don't get at all. What is the use case when I cmd-tab to an app but DON'T want it foregrounded? 🤷♂️
Anyhow, you have lots of choices to tweak how this works on Mac but the best one I found also happens to be opensource which is a great win-win:
