Tab Groups - Add option to show last active tab when the stack is collapsed

[Steeltent]

Often I use tab groups like a stack - read the top tab, closed it when done, read the next tab - rinse and repeat until the tabs are gone.

That works for all kinds of content - videos, articles, news items, social media.

When using tab groups in this way it is very convenient to have one tab of the group accessible even when the group is collapsed.

Right now the groups collapse down to the color coded group indicator. That saves space but makes my use case impossible.

So please add it as an option to collapse all but one tab of the group. Either on a per group setting in the context menu or as a option in the settings or config.
