What's New
Live Chat — You can now chat with everyone in your watch room. A floating chat bubble appears on the page that you can drag wherever you like. Unread message count shows when the chat is minimized.

Emoji Reactions — Send live emoji reactions (laugh, heart, fire, and more) that float up on screen for everyone in the room to see.

Custom Video Player — A new built-in player overlay with play/pause, volume, and a progress bar. You can toggle it on or off from settings.

Better Streaming Service Support — Synclify now recognizes and works more reliably with popular streaming services.

Nickname Support — Set a display name so others in the room know who you are.

Report a Problem — A new "Report" button in the popup lets you send feedback or describe issues directly from the extension.

Improvements
Smarter Video Detection — The extension is now much better at finding the right video on the page, especially on sites with multiple video elements (ads, thumbnails, previews).

Fullscreen Support — Chat, reactions, and the custom player now follow you into fullscreen mode.

Refreshed Design — The popup, settings page, and on-screen overlays have all been redesigned with a cleaner, more polished look.

More Reliable Sync — Improved handling when you navigate between episodes or pages without leaving the room.

New Settings — You can now individually toggle chat, reactions, the custom player, and volume sync on or off from the settings page.
