Cursor IDE

Describe the Bug

Hi Cursor team,

I’ll be direct: the pace and nature of your UI changes have become a problem.

I work in Agent Mode daily with the sidebar on the left. The ability to switch sidebar positioning was a small but important part of my setup — and it’s now gone. No announcement, no alternative, no explanation. This is not an isolated incident; it’s a pattern I’ve noticed across multiple recent updates.

I genuinely question whether UX decisions are being validated before they ship. Features that users have integrated into their daily workflows are disappearing, seemingly without a structured process for evaluating the impact. That’s not iteration — it’s churn.

I’d strongly encourage you to:

  1. Audit what you’re removing, not just what you’re adding
  2. Communicate breaking changes clearly and in advance
  3. Consider a stability channel for users who prioritize consistency over cutting-edge features

I hope this lands as the constructive criticism it’s intended to be.

Steps to Reproduce

  1. Open Cursor and switch to Agent Mode
  2. Attempt to move the sidebar from its default position to the left side
  3. Notice that the option to reposition the sidebar is no longer available

Expected Behavior

A setting or drag-and-drop option to reposition the sidebar, as was available in previous versions.

Operating System

MacOS

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, try Cmd+E Toggle Agent Layout. It should switch the sidebar position. That said, in 2.6.19 there’s a known regression where this command doesn’t always respect the user’s sidebar location setting.

If Cmd+E doesn’t help, try adding this to settings.json via Cmd+Shift+P then Preferences: Open User Settings JSON

"workbench.sideBar.location": "left"

Then restart Cursor.

The team is aware of the issue, similar reports:

I’ll also pass along the feedback about communicating breaking changes. Let me know how it goes.
