It would be better if columns with grades were ordered in the same way the activities (quizes / assignments) ordered in the course. Currently they are ordered according to the date they were added (from the oldest ones to the newest ones). Or at least consider adding "order by" function. Current state of things doesn't reflect the layout of the course making it difficult to work with.
