A place to make improvement suggestions?

I have am just starting to use code.org in my classroom (full time CS teacher for the entire elementary school) and I am very excited about how it is going thus far. I love some of the new changes that were implemented over the summer. I have several classes that are lower-level assisted classes (or resource classes) where the kids need a lot of careful control to keep them on task. I have several suggestions for further improvements to make the software more adaptable to kids with learning/behavioral disabilities. I couldn’t find a specific place to make those suggestions. Please point me in the right direction. Thanks!
