Hey, this is expected behavior. Editor Classic was intentionally deprecated in recent updates, so all users are now on the unified Editor layout.
The review controls moved to the breadcrumb and tab area at the top. We’ve heard this feedback from a lot of users, so we already added a setting: Settings > Layout > Review Control Location, where you can choose between Breadcrumb bottom, next to the code and Island top right. It’s available in Nightly right now, and it’ll come to Stable in one of the next releases.
About the agent chat max width, that’s a known UX difference between the old Classic layout and the unified layout.
Related threads for reference:
- Accept/Reject button somehow got on top again
- Agent multi-file review controls appear in the editor tab/breadcrumb area; I want the bottom “Undo / Keep” style back (or a setting to choose)
If you want the setting sooner, you can switch to the Nightly release track for now.
