I don’t work in programming, but in arts and academia. I usually have 1 “main” window in working in and at least 1-2 more I am continually referring to, so I like to be able to quickly switch between a single fullscreen window and a 2 column view. Typical workspaces for me are Zotero + Firefox + Word (for writing and research) and Photoshop/InDesign + Finder + Firefox (for design). When I do code, I like being able to have at least 1 terminal window side-by-side with a coding LLM. I usually also have a workspace with Spotify + MacPass + Telegram open that I refer to as needed.
