I don't understand why so many people building agents feel the need to fork and maintain a whole IDE as well
That’s also not how I think about ctx. The UI is a workbench around agents, not a replacement for IntelliJ/VS Code. If you need deep code navigation, refactors, debugger-heavy work, etc., the right answer is usually to open the same worktree in your IDE.
ctx includes surfaces for diff review and an integrated terminal, but not code editing or a full-fledged IDE. It's not a fork of VSCode.
