I would highly recommend using Arturo's skins to anyone that wants to save time/effort of developing their own, or those that wish to develop their own. 75% of what I learned about using P2VR and the skin editor came from the study of skins and widgets I purchased from Arturo a couple years ago. His work is impeccable.
Between this forum and Arturo's skins and widgets I was able to develop a custom skin for my Real Estate Tours:
I am excited about this new version of Pano2VR...While I have been using a different product for my tours the last couple years, with this new version I may consider giving P2VR another try. If so, the first thing I will be doing is buying Arturo's new Responsive Skins.
