A place to suggest domain-specific tools for teaching?

[choldgraf]

Is there a good place to suggest domain-specific tools that might be useful for teaching? e.g., I was going to suggest a link somewhere about mobilecelonian, @takluyver's port of the "turtle" app into javascript so that it can be run via notebooks/lab. Something like this might be really useful if they were teaching intro to programming with jupyter!

If domain-specific materials are out of scope then no worries, just wanted to see if there were a vision for this kind of stuff.
