Nit: I think the <button> tag might be a bit more idiomatic for this (using a
submit button technically also gives you a button, but I'm pretty sure dates
back to when HTML was mostly static pages and forms).

(And yeah, that also applies to the other existing buttons in here. Sorry, I've
missed that previously.)
