Requires yubitoggle to already be in your path.
yubitoggle-applet adds an app icon in your taskbar to quickly check the status and toggle your yubikey on/off. Tested on Ubuntu but should work on other Linux OS too.
The icons are shamelessly stolen from Yubiswitch.
The guide was super helpful in creating the applet: http://candidtim.github.io/appindicator/2014/09/13/ubuntu-appindicator-step-by-step.html
Improvements still to do
- Add yubitoggle directly so users don't need to manually add it to path
- Add install script to run on startup
- Handle missing gtk dependencies
