Matt, Thank you for sharing! It uses JS and non-deterministic! So, it should have the issue Jeremy noted! But based on your previous post, Jeremy and Mario note, also Mark explanation in another post ( https://groups.google.com/d/msg/tiddlywiki/jlBObreG30w/moxP900xBAAJ)
Is it possible to make it deterministic to address the performance issue? I mean generate a random number and freeze until a browser refresh?
