It would be great if the system could check to the exam entries, and if the exam has students eligible for extra time, that this be added on to the total time requirements for the exam. It is great just being able to drag the exam times around on edit mode, but when there are lots of exams which need staggering throughout the day, it is frustrating to always have to be considering if that exam has a later finish time due to students with 25% extra time. It would be lovely if this could be added on to the bottom of the "time box", ideally in a different colour, and this would make scheduling exams so much easier.
