Great plugin once its actually up and running!
So feature requests for future releases:
1. Support for Mutli-site WordPress installations by allowing the URL-Format variable to be passed from the site that is sending the push instead of a static setting for all sites using the server.
2. Support for the post excerpt being passed with the notification.
3. Interface for reading the device list from the .push table to show current number of subscribers. If someone was logged in when they grant push notification permission, ass the user name to the table row to allow easier identification of who subscribers are.
4. Last but not least allow sending to individual devices, specifically in the test push field, even if this means entering the device id for where to send manual.
Thanks again for making the plugin!
