/* This is a FluidApp userscript for Google Inbox on the desktop. 
Includes options for total badge count and unread badge count.

1) You need the paid version of FluidApp (http://fluidapp.com/)
2) Point Fluid to https://inbox.google.com (I recommend the icon from here: https://medium.com/@chrismessina/create-an-icon-for-google-inbox-in-your-dock-ed269312e3bc)
3) Set the user-agent to Chrome
4) Go to window -> userscript and add click the plus sign under the first table (on the left). Name the item 'Inbox'.
5) In the second table (on the right) click the plus and type in "*inbox.google.com*".
6) Paste the contents of this document into the script area below that.
7) Configure badge count (for total or unread only in the code below).
8) Refresh your FluidApp.

Some Caveats:
- This doesn't update the badge unless it's looking at the inbox. 
- The workaround is to only show the badge count when looking at the inbox, otherwise it shows '?'

TODO: Update count on item removal / read.
