1.2.0: Pinning a tab that is in a group is no longer undone when "Keep tabs in their groups" is on. Much faster with many tabs open: restoring or reopening a large window no longer makes the add-on do work proportional to every open tab. The one-minute integrity check now runs reliably even while the browser is busy, and the add-on recovers on its own if its startup ever fails. If a settings change cannot be saved, the popup no longer shows it as applied. Development tooling updated.

Tab Group Keeper 1.1.2

• Group locking now restores tabs more reliably when they are ungrouped or switched to another group in the same window.
• Cross-window tab moves remain allowed and become the new accepted layout.
• Separator tabs are moved behind the grouped block without globally reordering your tabs.
• Replaced configurable polling with immediate event-driven updates and a one-minute integrity check.
• Improved Split View handling on supported Firefox versions.
• Updated the settings popup for better accessibility and clarity.
