Hi,
I see a lot of code on 1 single page. For small algos that is oke, but some algos are quite large. I would suggest to have multiple pages/ tabs/ files so everything is a bit more structured. Maybe also allow some reuse over various projects. Code maintenance is hard..and if done incorrectly a small error can have dramatical effects.
Get some ideas from:
