This is a neat project but also replicates the functionality of many libraries (I'm not going to dig it up but there are more than a few of these floating around with varying amounts of maintenance). Anyone needing to use these seriously will quickly end up forking it. Also - I think the goal of EVERY UX designer should be to prevent the need of these kind of things AT ANY COST. It obviously varies by product and industry but any designer worth their salt will do everything they can to make it painfully obvious what a user should do at every step of the way.
