They are not being critic of your idea it's just that they have to keep CodeIgniter in a small foot print and fast.
Good luck on your idea and keep me post on how your making out with it. I also have an Editor that I bought along
time ago called Innova Studio Editor it works with all kinds of programming languages.
What did you Try? What did you Get? What did you Expect?
