Can you elaborate on what you find lacking/problematic in the Electron app? I find very little difference between it and any other proper desktop app. I'm on a 2013 MacBook Pro and I find it works very well.
Performance and resource usage mostly. It's a very, very good example of an Electron app, but it still shows its web flesh in various ways. Some reconnecting issues, incomplete page loads, UX weirdness (minor). Like I said, it's a great example, but that's like praising the beauty of an architectural masterpiece built on sand.
