For anyone who uses session replay tools to debug, monitor, or analyze user journeys, this feature might come in handy. OpenReplay — the self-hosted session replay tool that helps developers troubleshoot web apps faster — now supports tabbed browsing.

Here's how:

1. Capture and replay user sessions that span across multiple browser tabs, all within a single recording.

2. OpenReplay's tracker communicates across browser tabs, ensuring accurate tracking of each tab, even when duplicated or opened with `window.open` without `_blank`.

3. With "co-browsing", you can watch and support users in real-time and see how they navigate across multiple tabs of your app.

Why it’s important?

1. This feature is convenient for developers as it allows them to easily identify bugs by reviewing a complete session in one replay, rather than having to reference multiple recordings.

2. It provides a deeper understanding of the user journey and interactions across multiple tabs in your web app, helping in the comprehension of complex user behaviors and paths.

3. It provides accurate feedback on user tab actions such as opening, switching, and closing tabs, assisting in UX/UI improvements.
