Order classes according to time

Thanks for adding the option to add times to classes. Please make it to organise the classes according to time as well so that they can be in chronological order. Loving the work youre doing. If its not too much to ask, also add the option to select the days of the week. For instance, my lessons are always shorter on fridays, regardless of the 7 day cycle. so if day 2 falls on a friday, the lessons will be shorter on day 2.
