I've a update for you. All accounts will be show in a single screen, you can config which column will be show too. You can create a group (follow set) for account X and interest set for account Y, both can be use at the same time. I will show more demo video later.
Do you use an event kind to specify the feed like that?
Ah, I'm not use event kind for that. Each newsfeed define by user's contact list (default) or their follow/interest sets (NIP51). Lume just show its all into a single screen, and save the state when user close app into the local database, maybe save it into relay too with NIP78.
So, I am going to start defining some type of Custom Feed event type.

This is complicated by definition, but it would be nice to have a feed defined in Lume showing up on Amethyst.
as good a time as any to learn how to implement set operations
in Go i do them with for/range iterations and maps (which require mutexes because of concurrency)...
to be honest, a lot of C++ and other OOP programmers (java, rust) overemphasise the use of map/reduce operations, which are essentially set operations, but in my experience i need maybe one or two in a whole application and often this allows very specific implementations
