Reporting errors in timed practice
I just wanted to report an error during timed practice (it would not accept the word odour which is the British English spelling, in one of the Spanish lessons). However, I couldn't because time ran out and the dialog box disappeared.
Generally in timed practice it would be better if the clock was stopped whenever you weren't actually answering a question. This includes after answering a question, so you can read the discussion if you want.
