My laptop is getting old and i can't have Element eat up half of my RAM. There are many more clients out there but which one is good? aka "the best? ;-)

My requirements: lightweight, encryption 100% supported, active development/community. runs neatly 24/7 in the background.

Should also support the latest features, let me customize when to get notifications: priorities / muted chatrooms. And ideally also look clean and run on the Pinephone. But that's optional.

I don't care which desktop environment or cli.

What do you use?
