Translations:QS:Time limit disable prev/728/en

It allows disabling the "previous" button while a time_limit countdown is occurring. Normally, even if a time limit countdown is active, if the participant wants to click on "Previous" and move to the previous question or question group, they can simply click on the "Previous" button (thus cutting short the time spent on the question or question group). By activating this function, the previous button will appear greyed out and will not be available until the countdown timer has finished.
