I’ve tried it and really enjoyed how it works. I’d like to suggest a small UX improvement: for a typing app, it would be much easier to avoid using the mouse. When a practice ends, the user should be able to press the RETURN key to move to the next practice. (instead of clicking the Continue button)

Hey - thanks for trying it out :)

That's a good point - we actually do have keyboard shortcuts but their discovery is definitely lacking! Using the return key as the default seems more intuitive - thanks for the suggestion!
