Tab Groups Sync од Eger37

Tab Groups Sync lets you organize your tabs into groups and switch between them instantly. It is an independent fork of Simple Tab Groups by Drive4ik (MPL-2.0), adding two things on top:

• Cloud sync across devices via your own private GitHub Gist — your groups and tabs stay in your GitHub account, never on a third-party server.
• Group-scoped pinned tabs — pin tabs to a specific group instead of globally.

Features:
- Create, rename, reorder and delete tab groups
- Switch groups via popup, sidebar, hotkeys or context menu
- Multi-Account Containers support
- Backup and restore your groups and settings
- Dark theme and custom icons

Sync is optional and off by default. It stores data only in a private Gist you control, using a token you provide; nothing is sent to the developer.
