Thanks for your work on this very helpful feature!
When I run the command "View File on Github" I receive an error in the console:
Traceback (most recent call last):
File "./sublime_plugin.py", line 356, in run_
TypeError: run() got an unexpected keyword argument 'url'
Also I'm confused as to which plugin, if any, you intend to continue supporting... githubinator or githubify? I see that they've both recently received patches.
