Hey, this is a known issue: the sidebar position resets when you switch layouts with Cmd+E. This was fixed before, but it looks like the regression is back.
Try this workaround: open settings.json (Cmd + Shift + P > “Preferences: Open User Settings (JSON)”) and add:
"workbench.sideBar.location": "right"
Then restart Cursor. Honestly, it doesn’t help everyone, but it’s worth a try.
Related threads, if you’re interested:
- Primary Side Bar forgets its position
- Primary Sidebar position resets to left on new window/project (v2.5.17)
Let me know if the workaround helps.
