I think the killer feature in this release is the background GUI use.

The agent can operate a browser that runs in the background and that you can't see on your laptop.

This would be immensely useful when working with multiple worktrees. You can prompt the agent to comprehensively QA test features after implementing them.

What if you want to develop desktop apps?
