Makes working with IPython Notebooks easy Rated 5 out of 5 stars
If you work with IPython Notebooks at all you know that reading the raw notebook is definitely not the right way to go. Thankfully http://nbviewer.ipython.org/ displays the rendered form of the notebook, but finding a notebook, copying its url, navigating to nbviewer, and pasting in the link can be time consuming if you do it a lot. This add-on lets you simply click once in the add-ons toolbar and it will automatically open the current page in nbviewer. It even works on non-raw links in GitHub. Awesome!
