I'm looking for a way to create a custom feed of multiple Lemmy communities. Reddit does something similar, calling it "custom feeds" or some clients refer to it as "channels." I've attached an image of my custom reddit feeds from the Satelite desktop app.
Use case: You could combine a bunch of news communities into a single custom feed, so you can have a feed that's filled with news.
Sometimes I want to view just news, but I don't want to unsubscribe from all the non-news communities I follow.
Is there any Lemmy client that makes this possible? Currently I use Jerboa on Android.
Are you referring to multireddits?
I don't know about the clients, but you can recreate this feature with RSS by combining all of your communities in an RSS feed app. For android, you may check out Read You, available on F-droid.
