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.

Wow, okay. Thank you for this.

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.

The recommended action when your CPU can’t handle it is to switch the mode to Filter or Filter+ instead of Dynamic. It’s not as good looking but it does darken the website at least.
