Feature: Two feature requests

1. Show a pop-up notification when a message is received.

2. Show a number on the icon in the tray to indicate how many unread messages there are

Example:

[Aetherinox]

Notifications are currently being implemented via the package:

• https://github.com/Aetherinox/toasted-notifier

Currently working on ensuring they work for all operating systems, Windows, Linux, MacOSX. It's almost done for the most part, just need to integrate it into Electron for shipment.

I'll look at adding an indicator after the major stuff is done.
