Hi @atian25, sorry for my very slow reply here. I wanted to eventually review this PR in detail but did not find the time amongst other responsibilities. Since this will not change in the near future, I decided to no longer maintain this repository.

Still, a few thoughts on your concept: I really like the idea of transforming data through a simple callback function. However, I believe it would be better to publish that as an alternative package, since many of the other config options would no longer be needed.

If you do (or did) publish this somewhere for people to use, feel free to add a link to #55.

I'm closing this PR and the related issue since this will not be merged anymore.

Anyways, thanks for sharing your suggestion!
