 **All repositories** is also opt-in and starts six paginated Actions request streams per repository on every refresh. Combining it with **Owned and organizations** can consume substantial GitHub API capacity in large organizations. Use **Recent repositories** or **Off** for a bounded scan, and increase the refresh interval when broader monitoring is required.
 
+**Open links** controls where notifications, pull requests, issues, workflow runs, and repositories open. The default **Browser tab** keeps the historical behavior in any browser. **Web app window** opens each link in a dedicated Chromium app window via `omarchy-launch-webapp`, and **Web app window (reuse)** keeps a single web app window: any open GitHub web app window is closed and the clicked link opens in a fresh one. Both web app modes require a Chromium-based default browser; with any other default browser they fall back to launching Chromium directly.

 Set these options from the command line after installing the plugin:
