Nicely done, but if you are really trying to be a framework for internal apps (vs a design framework like bootstrap) - I would focus on adding a couple of more admin-like components (such as grids vs tables with the options associated with grids).

An opinionated admin framework would be a huge win. For what its worth - semantic-ui.com has a couple of neat compenents that are also worth having (cards, steps/wizards).

Watching this project now!
