Question about size, build

I just discovered this project, thanks for making it. This looks really good.
### How big is this?

I was curious about the size of this as a library - I see a distributable of 124.45k minified. Is that all just this project's code?
### Does a targeted build exist?

I'm wondering if this project is structured in such a way that a targeted build could deliver a meaningfully smaller lib with just the features/elements required for an app ( Apologies in advance if such a build already exists ).

Thanks again for this awesome library, and for considering these questions.
