Hey, thanks for the feedback. I get the frustration. This change in Cursor 2.3 broke the workflow for a lot of users.
The button to toggle chat was removed on purpose in favor of customizable layouts. Here’s how to hide chat now:
Quick fix:
CMD+ALT+B(orCTRL+ALT+Bon Windows) to toggle the chat panelCMD+Eto toggle the Agent layout
Alternative (if you want the Agent sidebar instead of fullscreen):
- Gear icon (top right) > select Editor layout
CMD+Ito toggle the Agent sidebar
The gear icon also lets you set up and save a custom layout.
I know hotkeys aren’t a replacement for the button you’re used to. If you want to share feedback about this change, the team is collecting UI comments here: [Megathread] Cursor layout and UI feedback
