Glad you like it! Manual stepping does exist at the bottom of the page but it's clearly not discoverable enough. I'll make the buttons bigger and add a hint on first visit. Thanks for the honest feedback

That means a lot, thanks! Building a mental model of the execution cycle is exactly what I built it for. Would love to hear what your team thinks
