From a UX perspective, I find the way you've used colors a little misleading. The teal-ish color represents P2 of the first animated block, but is also the color of the second animated block. I think this leads one to believe that the teal handle in the graph is modifying the second block in some way rather than the first. I would suggest using a third color entirely for the second block and the selected curve on the right.
If possible it would be nice to have the colors of the two handles somehow both be similar to the color of the first block.
Oh, and thank you for this wonderful tool!
