Interesting. I want to create a system library but It's funny I
don't know a lot of low level stuff yet. Tho this also makes it a
great and even more enjoyable journey :P

That's great! It's much easier to me to just let the first
behavior anyway that will do! I also posted on [cboard

the same answers so this is how we'll do it! Thanks a lot for
your time and happy holidays!
