I want to be able to go in to "work mode" by clicking a button (typing a command). How would you go about writing a script on MacOS that you can run to open your "work mode" programs? Preferably on different virtual desktops and set window sizes? For example: Slack and Mail on one desktop, Chrome with specified tabs on another.
