Keybase has been one of the very few performant and usable "new-style" applications that I've used -and the only one of its kind.
Sadly I am forced to suffer electron-based vomit every day -between Skype, Teams, Whatsapp, Hangouts, Facebook messenger and whatever else I might be fortunate enough to be forgetting. It sucks that I might have to be on the lookout for a decent encrypted chat application that I don't actually hate, again.
Not sure why the use-case of chat communications has been afflicted by so much crappiness -as if it's a curse.
