This is a prototype app I wrote for debugging and visualising app state in mithril.js apps. The intent was to improve on console.log style debugging, especially on pages with rapid state changes (e.g. frequent mouse events or input events).
It has been somewhat useful for me, but not as much as I originally thought. There are also some known issues/bugs.
I may come back and revamp this project at some point, but right now it isn't a high priority.
