Can't use Agent Mode with sidebar left anymore

Hey, try Cmd+E Toggle Agent Layout. It should switch the sidebar position. That said, in 2.6.19 there’s a known regression where this command doesn’t always respect the user’s sidebar location setting.

If Cmd+E doesn’t help, try adding this to settings.json via Cmd+Shift+P then Preferences: Open User Settings JSON

"workbench.sideBar.location": "left"

Then restart Cursor.

The team is aware of the issue, similar reports:

I’ll also pass along the feedback about communicating breaking changes. Let me know how it goes.
