Hi, glad to hear you like the idea behind Tabs Tray!
Good news: tab-group support is already on the roadmap and will be included in the next release.

I apologize for any confusion caused by the GitHub organization link. Tabs Tray is not open source. The organization is reserved for a future roadmap that will host documentation, user feedback, and discussion. I'll update descriptions to avoid any further misunderstanding.

Tabs Tray is still in its early stages and remains immature in many respects. My immediate focus is on making it stable, useful, and reliable.
That said, privacy has been a priority from the very beginning: Tabs Tray requests only minimal permissions and adheres strictly to extension guidelines. Currently, Tabs Tray works completely offline and makes no external network connections.

I'll be updating the privacy terms and security documentation to ensure full transparency about what the extension does and does not do. Should anything change in the future, users will be clearly informed.

Thank you for your feedback, it genuinely helps make Tabs Tray better!
