New: every quiz card has "I know this word" (retires the word) and "Report a mistake" (hides the card while it gets fixed).
Fixed: the result line no longer flashes "✗ undefined" right after you answer.

You can now use LingoPop without an account: install it, pick a language and start. Signing in with Google is optional and keeps your progress across browsers.
New words now come in order of how common they are, starting with the most useful ones.

0.1.2: Pop now asks once, a few days in, whether you'd like to rate LingoPop (after a correct answer; "Later" snoozes it for a week, "No thanks" ends it). Settings has a new Help > Send feedback link. The version shown in Settings is now always correct.
