Thanks for sharing this. Great work!. I was wondering if it would mark a second time and third and I could test it in the small demo. It meet my expectations :) Great work!

Two humble suggestions: - the glare effect in the text "Damn fast easy marking with serializable selections" made me think for a sec that this library was about different thing that I though. I'd remove that effect and mark the word "marking" in that text, so the slogan it's already a demo.

- If the library support marking in different colors show it in the demo would be awesome. or maybe in different advanced demo
