1. Have your application look and act like a standalone application rather than a webpage—Chrome tried to support this with application shortcuts (or whatever they were called), but it never worked well enough
2. Give your application access to native APIs and capabilities that you can't get through the browser, like direct filesystem access
But it doesn’t act like an application. Most of the OS right click services, keyboard shortcuts, menu items are all missing. Accessibility tools don’t work.
It doesn't feel like one either. It feels like a shitty web page, and it costs 500$ to run. I can run apps in python and they don't feel the same way, never mind native.
They are talking in the context of games though, for which there aren’t such strong conventions, besides lives in your applications folder, and runs full screen.
