Kinda just alt+tab from Windows on Mac.
The premise
How it works
By default altab overrides ⌘+tab, but there are a few other options for bindings and you can use the stock app switcher alongside altab if you want. If you uninstall or quit altab, normal functionality of the stock app switcher is restored.
If you want you can give the app screen recording permissions, this lets it show window previews, no data at all is ever sent from the app but if you decide not to allow screen recording, app icons will be shown instead :D
