With Caffeine you can use whatever JS or Smalltalk UI framework you like, including React and morphic.js, a standalone JS implementation of Morphic from UC Berkeley's "Snap!" project that is much faster than Squeak Morphic at the moment. Another good hack is to use Squeak Morphic, but draw each morph on its own canvas. That relieves a lot of the computational burden on SqueakJS. There are examples of all of these things in the Squeak workspaces on the Caffeine page. Thanks for checking it out! Craig
