Pause timed practice between questions for error reporting
During timed practice, I very rarely report when a question has an error, because it costs me time to do so. As a solution, I propose that the clock should stop in between when the "Check" button is clicked and when the "Continue" button is clicked (i.e. after one question is finished, but before the next one is started). It is sometimes possible to see a formulation in timed practice that one does not see in the initial lessons, so in that case this change would also allow users to go look at the discussions if they are totally lost.
This will kind of break the spirit of timed practice, when you have to think and reply quickly without pauses, switching from one task to another. But I believe it would be fine to have an option to go through the tasks after you finish the session to analyze your mistakes, read comments or report program errors.
