That would be cool and not too hard to do. I can promise to write all the functions needed at the JS graph_editor side. However, I am still kinda clueless on the sage interact side.
It would be nice if there was something like "developer's guide to interacts", explaining the logic behind interacts and the minimum code to get a new interact (with any random JS) into Sage. Considering this is the second request for interact extensions (there was the sage bounty), seems to be quite a desirable direction to go. Also the small matrix editor I posted a few days ago, could be wrapped as matrix interact.
