Hey, this is a known limitation of the new Glass layout that shipped in 2.7.0. Glass replaces the auxiliary bar secondary sidebar with its own panel system, so extensions like Claude and OpenAI can no longer show up as tabs next to Cursor chat.
Right now, those extensions need to run from the Activity Bar left sidebar. The functionality is still there, it’s just in a different place.
There’s already a main thread for this request: Secondary Sidebar not supported. The team is aware of it. There’s no timeline yet, but your report helps with prioritization.
Let me know if you have any other questions.
