Describe the Bug

Previous when I used to open the Claude Code IDE it always open a separate panel on right most side of the window and while editing the changes used to appear it on the main panel (where I am writing code the left area).

Now it appear in the left panel (main window) and changes keep going right. even when I drag drop it to the right the changes keep coming in the same window.

It feels weird and difficult to work in this way

Steps to Reproduce

Open the Claude Code
Move it to the Right Side
Do Some Changes in a file

Expected Behavior

Like the previous version

Does this stop you from using Cursor

Sometimes - I can sometimes use Cursor

Hey, this is a known change in Cursor 3.0. The new Agents Window replaced the secondary sidebar (right panel), so extensions like Claude Code can’t open there like before.

A couple things you can try:

  1. Open the Command Palette with Cmd+Shift+P, run View: Reset View Locations, then Developer: Reload Window. This can help bring the extension back to the activity bar.
  2. After that, try dragging Claude Code from the activity bar into the sidebar. Recent updates brought this back.

There’s an existing main thread about this issue: Extension no longer supported in second sidebar. It describes the same case with Claude Code. The team is aware, but there’s no timeline yet.

Let me know if the workaround helped.
