Poor UX is an implementation problem, not an Electron problem. The popularity of well-built apps like Slack, Atom, and VSCode would seem to indicate many, many people have no problem with the UX.
In this thread you'll find many native app developers who are dismissing Electron because they feel threatened.
Cross platform apps are the future. Each day I run at least three Electron apps simultaneously and have no problem whatsoever. You have to be paying close attention to notice, and the reality is that most people do not care.
In fact, I was so intrigued by Electron, that I started developing my own app. So far the experience has been pure bliss.
