I have a windows store js/html app which I plan to re-release on electron. It features a rich text editor and a few other features. I want to release on Linux and mac os. Should I go away and learn qt/gtk/wx? Restart the whole project in Java? The idea that I might choose electron for ease/speed of development rather than use a leaner platform is being shit all over as a "business" decision. Not a "I don't have enough free time to learn two new languages and ui systems code three new apps" decision.
