Cursor 2.3: Layout Customization and Stability Fixes

Cursor 2.3 brings layout customization with four presets, 32 stability fixes across agents and UI, and extension process isolation. Rolling out over the week.

TL;DR

New layout customization system with four presets and keyboard switching (⌘⌥⇥)
32 stability fixes across agents, chat, code review, and UI
Extension process isolation to prevent codebase indexing from blocking agent work

New

Layout customization — Switch between agent, editor, zen, and browser layouts with ⌘⌥⇥ (or add ⇧ to go backwards). Layouts persist across workspaces.
File explorer quick access — Click repo name in top nav to view file explorer; now defaults open during onboarding.
MCP OAuth improvements — Static Client headers support and new auth tabs for previously authenticated servers.

Fixed

Agent stability — Fixed edit bugs, parallel agent rollback issues, worktree file deletion, and model mismatch in Plan Mode. Improved auto-run preference handling to prevent unnecessary approval prompts.
Chat and UI — Fixed chat loading after restarts, Plan Mode focus stealing, Windows browser menubar, and pane selection reset on upgrades.
Code review — Fixed keep/undo buttons not appearing and improved diff view visibility when scrolling.
Extension isolation — User-installed extensions now run in separate processes from built-in Cursor extensions like codebase indexing, improving overall stability.
Browser and layout — Fixed multiple tabs support, terminal display on right-side layout, and bottom-of-screen content cutoff.
