It looks like we will have one less reason to ask about a native application (personally I never asked for it though) over the responsive design. Chrome 42 is adding support for notifications and other browsers are also heading towards the same directions, but it will probably take a while before it gets a unified implementation. http://blog.chromium.org/2015/04/reaching-and-re-engaging-users-on.html
Looking into the developer documentation for push notifications on android and desktop (chrome) and seeing the examples springing up in the wild, I wonder how long it will be until someone releases an alternative solution?
I love digitalpoint add ons, but this is just out of my price bracket.
We are holding off until that until we allow our users to use it. Without the data attribute, you can't do things like tell the user what the notification is *for*, or send them to a specific URL when they click it. Basically right now all you can do is be like, "Yo... you got a notification. Sorry, can't tell you what it's about or the URL it's related to." lol Kinda silly right now.
