I get it. That’s why I use Plus messenger. It’s a better, more customisable UI. Private chats, groups and channels are on a different page, if you want it.
Unfortunately I use Discord, WhatsApp, Signal, Element (Matrix) and SimpleX all combined because my contacts are spread out. Looking forward to secure interoperability.
Plus Messenger looks proprietary. You might be interested in Beeper once it’s released, it let’s you use all your messaging platforms in one app. And it’s supposed to be secure and open-source.
