Onward to the checklist!
[Like my code tester, this will be a permanent link, so come back to it anytime you like!]
This has been a looong time coming for me, haha. I've said more than once that I wanted to make something like this for you guys, and it finally happened! Be sure to click things, test things out, the whole nine! I didn't go too overboard on it since I wanted to host it here and not on my site (which eliminated JS), but I think it does the trick. Enjoy! <3
