How is it possible to have a add-on run immediately after you open blender? What I am needing to do is that when I open blender it toggles the add-on. The add-on that I am using is the Virtual Reality ViewPoint. What I want is for that addon to activate right when I open Blender.How is this possible?
If you launch blender from the command line, you can designate a startup .py file which could either be the addon itself or trigger the loading of the addon. 

Sample cli command:

blender --background --python startup_script.py


Depending on your OS, there are different ways to make the command line call clickable as an executable app for convenience.
