I've tried a large number of apps in search of something to replace multireddits. Summit for Lemmy is the only one which managed to implement this under its multi-community functionality. The app is being consistently updated with new features and I do not feel like I'm missing out on anything other apps offer.

I'm still looking for a keyboard with predictions which doesn't require me to change languages manually. I'm currently on Gboard as there is no decent alternative.
