Sublime Pebble 
Sublime Pebble aims to be the ultimate package to help developers write watch faces and applications for their Pebble devices.
This is a work in progress, so there isn't much going on yet, but it will be improved upon!
Installation
You can install via Package Control, just search "Pebble".
Commands
Sublime Pebble uses the command palette to respond to these commands:
buildcleaninstallscreenshotpinglist
You can also supply a custom command (without parameters at the moment).
Completions
Currently there are only completions for the Foundation set of modules and a subset of the constant values.
