Very good! I think that those who like animes and japanese culture will like a lot. This extension was built with quality in mind, i think that the character have a great contrast with the most popular background colors(white and black). That said, it gives visual studio a very nice look.
Thank you for your question.
The customization is new feature in 2013.

This Pronama-chan IDE 2012 has same function as the Pronama-chan IDE 2013.
