Hello

Is it possible to extend this module to perform similar functions like they have done for the wordpress version. Over there they have over 40000 installations which means everybody is asking for this.

https://wordpress.org/plugins/onesignal-free-web-push-notifications/

Features:

Supports Chrome (Desktop & Android), Safari (Mac OS X), and Firefox (Desktop) on both HTTP and HTTPS sites.

Automatic Notifications – Send notifications to followers every time you publish a new post. Or set up a reminder that gets automatically sent to them if they haven’t visited for a few days.

Targeting Segments – Send notifications to specific visitors based on language, number of times they’ve visited your blog, or even set up your own user attributes that you can target.

Opt-In Customization – Choose when and how to ask your visitors to opt-in to browser notifications. Customize the prompt they first see.

Real Time Analytics – See your notifications being delivered in real time, and watch them as they convert into visitors.

A/B Testing – Try out different messages to a smaller set of your visitors to figure out which messages are more effective and then send the more effective message to the rest of your visitors!

Scheduled Notifications – Schedule notifications to be delivered in the future, based on a user’s time zone, or even based on the same time of day they last visited your website.
