locked The home page
Question for you: do you use the 'combined message view' that's presented when you go to https://groups.io (ie. All Messages)?
If it's not being used, I'm wondering if instead if would better to make the Subscriptions page (https://groups.io/groups) be the home page. And I'd move the functions to view/modify your muted/followed threads/hashtags into each group. And there'd be no combined message view.
