Since i picked up a G13 I was looking for a way to get it to display info from Elite and my applet search led me to this post on Elite Dangerous Codex.
Its a companion app for your keyboard that has a few features. Depending on which keyboard you own, you can get the following features:

Logitech G15 Keyboard Software

Status: System information when you arrive in system. Includes Allegiance, Power Play status, Population, Economy and Government.
Space Traffic Control: Make it sound like you are hearing radio calls from stations and ships (configured to only happen in SC with Volume and density of traffic).
Galnet Ticker: Galnet News on a Ticker Tape
Reddit Elite Dangerous Ticker: Latest posts from the Elite Dangerous Reddit.
Radio Controller: Preconfigured for a few ED specific stations, but customizable.
Play Spotify Premium: If Spotify is your Jam, you can use this to control it. Includes a few Space Based playlists.
Elite TV: A few Elite Dangerous based Youtube Channels.

It works on the G13/15/19 keyboards, but I had an issue with the program and had to go back to an older version first before I was able to use it. If you have a G13 I will post instructions here to fix the issue if it happens to you.

Also, if you DON'T have a G series Keyboard, you can still use this app. it will give you a little window with most of the features to enhance the game for you.
