New feature: You can now pin your favorite communities
Pinned communities stick to the top of your community list, and your feed will lean a bit harder into them - you'll still see everything else, just more of what you actually care about.
To pin: hit the pin icon next to any community in your list, or use the ... menu on the community page. Same to unpin. You can pin up to 100 communities.

Curious what people pin first - let us know in the comments!
Thanks to @DNYLND @SomewhereInNevada22 @KinQuro and @Menkyo for the suggestion.

I pinned the Community I moderate first, then pinned communities I post in regularly, followed by communities I just like to keep up to date with.
Then I realised I'd pinned everything, so unpinned a few.
I am so pin challenged. coffee please
