On the other hand, your core service has yet some things that must be fixed / perfectionated (I'm talking only about Cordova). I also think that you should consider geo-tagged notifications, which is a very important need.

On the Cordova side of things, I would like to know more about what needs fine-tuning. Docs? definitely need work
And our push plugin is a wee bit fat for Android, needs to go on a diet, dexing takes a while

Once the modularisation of android is complete the push plugin will be the first to benefit from that.

And the JS API needed some clean-up, you have seen Erik's proposals on that item
