I found a small bug in the yeast pitching calculator. If you mark the "Starter - Step 2" or "Starter Step 3" then go to another page and hit BACK on your browser, the checkbox gets out of sync, ie. it may be marked but the step info is not displayed or vice-versa. You can see this in the screenshot: In the screenshot you can see that Step 2 is checked but closed and Step 3 is unchecked but open. I guess the problem is that the page opens/closes the info when the checkbox is clicked ("onClick"), regardless of what the actual value of the checkbox is. I'm running Chrome (Version 24.0.1312.52) on Debian.
