Code editor & LSP

Switch the workspace right pane to Code when you want the file tree, editor, and terminal. Code view in the workspace

​
What you get

  • File tree — open and navigate project files. New file, New folder, and Refresh sit at the top of the explorer
  • Search — search in files (Cmd/Ctrl+Shift+F)
  • Editor — Monaco-based editing with tabs. Markdown files can toggle Preview / Code
  • Language intelligence (LSP) — completions, diagnostics, and go-to-definition for common languages via the project sandbox (TypeScript/JavaScript, Python, and others depending on the stack)
  • Terminal — interactive shell in the private workspace (`Cmd/Ctrl+“ to toggle)
  • Editor settings (gear) — font, wrap, tab size
On a phone, the file tree is a drawer (folder button) — there is no always-on sidebar. Free accounts see a read-only banner in Code. Pro can edit files here. Chat (Build) still writes files on every plan.

Tips

  • Prefer asking Mythex for large changes so checkpoints stay useful
  • After installs, watch the terminal for errors
  • Use Restore on a checkpoint if an edit goes wrong
