My main gripe - how on vanilla MacOS alt(cmd)-tabbing cycles through applications first and then _all their windows_ rather than windows first, doing _nothing_ on a per application basis. I cannot imagine how this matches at all to anyone's workflow. Nobody at apple works on a single project across multiple applications (documentation in browswr, your IDE, an emulator, some terminals, etc.).? You have to install a specific app and give it some crazy permissions to fix those issues. Pfft
