@TacoTheDank This is great. Will need some time to review it. Nice work!

Special thanks for spelling mistakes fixes. English is second language for me and usually I am too lazy to verify it.

quick question: can we have gradle task or a script for verifying code style using editor config?

I don't think there's a gradle task for it. I think it sets the codestyle automatically while editing.
