Thank you for this @ataffanel.
I would love to write some code based on yours, for the UI of a project of mine. Please note that the project is completely non profit.
I would publish my code under BSD license but, since I couldn't find any mention of licensing in here, I would ask if you're ok with the idea.
Be sure that I would give credits and point to your gist in the published code; in case you want to know more about the project first, please feel free to ask.
