Feature request: fewer clicks. It should be one click per question

I'd suggest a "toast" would suffice for the correct answers. Proceed to the next question when correct, with a "next" button when incorrect.

another feature request: add a skip or "don't know" option. if i truly don't know a word then a lucky guess would inflate my score.

Keyboard shortcuts would be nice as well. When I saw it was 100 questions I bailed.

It should be zero clicks
