TMS 8.1.0 is a significant feature release. Tab Groups are now a first-class citizen, favicons are more reliable, and the suspended tab page can now follow your OS theme automatically.
What's new
Tab Group support
TMS will now save and restore your Tab Groups across version upgrades and session save/restore operations. Groups are preserved with their names and colors. This was the most requested feature since the MV3 rewrite.
Automatic theme
A new System option has been added to the theme selector in Settings → General. When selected, the suspended tab page follows your operating system's light/dark preference automatically. The existing Light and Dark options remain.
More suspend intervals
The "Suspend automatically after" dropdown now includes additional minute-level options, giving more fine-grained control over how quickly inactive tabs are suspended.
Favicon reliability
Several improvements to favicon fetching and caching make the icon shown on suspended tab pages more consistent, especially in Chromium-based browsers like Vivaldi.
Session Manager shortcut
A dedicated quick-access button to the Session Management page has been added to the extension popup, so you can reach your saved sessions without opening the full settings.
