I was thinking it would be really nice if you could download scripts from the website or the app itself. Things like controls, sprites with physics or walking animations would be super awesome if they could be downloaded instead of having to make them yourself everytime you need one of those things. IDK maybe its just me but it would be really awesome if that would happen

I forget what it is, but I think there is already a site for that.

The scratch resources website. It's never updated though, I keep trying to submit things and they never get added.

I don't support, then every game in the site would use those and creativity would go away.
