Feature: Filter communities while taking into account Home instance defederation list

[lionirdeadman]

What do you want to see?

When I set my home instance, it would be nice if the communities list didn't show communities that the selected home instance won't connect to.

Additional context

Example:

Someone who sets their home instance as lemmy.world should not see a community from exploding-heads.com.

That's a great idea. I think I already have everything to support this in the frontend. Just need to find some time to code it up.
