I really don't understand people who are 'disappointed' with anything that uses Electron. Sure, it's not as performant as a native app, but writing and maintaining a different native app for every platform you wish to target, and then keeping their UIs united, is unreasonable for most people.
I'd be more disappointed if they didn't use Electron.
I don't like bad software. Almost every Electron app that I've ever encountered was quite bad. They are laggy. Installers in hundreds of megabytes and installed apps are even bigger than that. Yes, it's not that much on it's own but they compound. Even React Native approach is superior to Electron and it's possible to do better than that while not developing separate native app for every platform.
