The NetLinx: New From Template commands will insert code into a blank view (tab), or create a new view if the active one contains text. The former makes it quick and easy to create a new file in the correct folder with the correct name by using the Sublime Sidebar (View -> Sidebar). Following the Sublime Text philosophy of being customizable, these templates are located in the Packages\NetLinx\templates directory and can be modified or replaced as you desire.
NOTE: If you installed this plugin from the .sublime-package file, you will have to open up that package to modify the template directory. If you plan on modifying templates, you should seriously consider installing via version control.
