## Description

StreamStack — Watch Multiple Streams at Once
StreamStack automatically detects live video streams playing in your browser tabs and lets you watch them all at the same time in a clean, organized grid.
Perfect for sports fans who want to follow multiple games, matches, or races simultaneously without switching tabs. Also works with gaming streams and identifies most streams. 
How it works
Open your streams in separate tabs as you normally would. Click the StreamStack icon and it instantly finds all your active streams. Choose your layout and hit Open Multi-View — all your streams appear together in one view.
Layouts

2×2 — Four streams in a grid
Spotlight — One main stream with others in a sidebar. Click any sidebar stream to bring it to focus.

Features
