This plugin is still in the very early stages of development! I'd highly recommend you experiment on a test unraid server and/or a test music collection!
The plugin's port is configurable and defaults to 9090
Google authorization is done on the plugin's webserver itself. It'll give you a URL you can go to and authorize your Google account. Adding and removing of watched paths is done on the plugin's 'config' page.
These are some plugins I've written mainly to make my own development easier, so they're specific to me. If people want I could make them more generic and configurable.
Pretty self explanatory. Installs my .vimrc by default.
Installs git. Defaults to my name and login info.
