Hi Floutsch!

First of all, thanks for compliments! There's never enough of those :)

Regarding your request - The whole point of the extension for me was to have an auto grouping of my tabs, so that is by design.

BUT, I do plan on implementing custom rules, so I suppose it would be possible for:
- auto grouping on
- Custom rule: Disable grouping for all domains, except specified whitelisted domains such as X, Y, and Z.

If that's what you mean, that's a good idea! So stay tuned for updates :)

Also, if you have any other requests/questions/bug reports, feel free to update me on the support page (it's in this extension's bio and description).

Cheers! 🍺
