Doing the same more or less, replacing vscode for vim. Usually three/four panes open, one codex running in a container so it doesn't share my host filesystem, one pane for git diffs/git, one for general shelling and one for neovim basically. One of these per project/task/worktree I'm working on, usually 1-2, maximum 3 at the same time.

Not sure what all the other folks are doing, but the industry/ecosystem tends to over-engineer every single thing instead of just working on the thing, while I just want proper code, proper design/architecture, and proper high-quality results.
