Sticky Tab Groups by Eric Blanquer

Sticky Tab Groups keeps the tab groups you choose immediately after your pinned tabs.

<b>Keep Left</b>: use the toolbar button or the tab context menu to keep a group at the left edge of the tab strip. Use Release to stop.

<b>Open New Tabs Outside Sticky Groups</b> (enabled by default): new tabs opened from a sticky group are moved out of it.

<b>Auto Select Last Selected Tab</b>: opening a group activates the tab you last used in it.

<b>Auto Collapse Groups</b>: an opened group stays open so you can pick a tab, then every group collapses when you select a tab or click, scroll, or type in the page.

Collapsing on page interactions needs optional access to all websites, requested only when Auto Collapse Groups is enabled. The toolbar button shows "!" while this access is missing.

The extension collects no data.
