All nice and dandy, but please, for the sake of everything, can this site just stop auto advancing on steps?! I click the last one and advance a step before I can comprehend what this command did or read any context. Breaks flow completely... And I'm just able to be fine advancing manually once I feel I'm done with the current step. Other nits: * show the ;; in the step code snippets, at least at the beginning - else you may be confused fast if you hack around in the "terminal" * add a 'run this snippet now' button to the code snippets, a small green triangle or whatever those IDEs are using nowadays, allows to copy of examples either modifying before execution or - like me - paste them in a "real" OCAML REPL I have on my desktop. don't get me wrong, the site and idea is nice, those things just irritate me, almost irrationally, from an UX POV.
