Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

The agent sidebar is on the left after the latest update and my file browser is on the right. I don’t want my code on the right please. None of the help topics about any of the menus are correct anymore. There is no option to “Move Primary Sidebar Left” at all. None of the old helps cover how to move the primary sidebar.

Steps to Reproduce

Open up cursor, open the primary sidebar. If it is on the left, you have reproduced the issue. If it is on the right - tell me how to move it to the left.

Expected Behavior

when I update cursor, the layout of my IDE should remain the same. This includes where you believe the primary sidebar should be located by default not having any effect on my current layout.

Operating System

MacOS

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey @hemmick, thanks for the report. Your layout isn’t lost!

What you’re seeing is the Agents Window, a separate agent-focused window that Cursor now opens on launch when no other windows are restored. Your IDE layout with the file browser on the left is still intact: from the Agents Window, use File → Open IDE (or run “Open IDE” from the command palette) to get back to it.

To make Cursor open your last-used windows on startup instead, go to Cursor Settings → General → Startup and set Window Restoration to “Last Used Windows”.

Aha! Thanks! I didn’t realize the entire window had changed - IDE mode was exactly what I needed!
