Focus mode for a specific tab group

[hi_bye]

I'm starting to horde tab groups like I horde tabs and can get easily distracted with all of them open. This isn't too much of a problem most of the time, but sometimes when I'm trying to work on a specific task, usually within a single tab group (which is usually how I group my tabs), I often end up clicking into other tab groups and down other rabbit holes. 

Feature request: a focus mode for a single tab group that would "mute" or hide all other tabs and tab groups while I work on a task. It can be set for a time limit or just quickly enable/disable it via the context menu. 

Not sure if other browsers have this or maybe there is already a better workaround (if so let me know), but I think it could be a great boost for productivity.

I came here to suggest the exact same idea. Please set this up. Even if you don't horde tabs, we all end up having multiple open because we are always working on many projects at the same time. It would be incredible to have.
