I'd like to make the suggestion that you make scrolling in reports a little more user friendly. I use the Course Completion and Activity Completion reports and have many people taking courses. There are also many types of activities they need to complete.
It would be helpful if the names of students locked in place on the left when scrolling across the activities, and if the scroll bar at the bottom was set so that you didn't have to go all the way to the bottom of the page to scroll to the right.
The problem I have is trying to track who is actually doing what without printing the report on an Excel spreadsheet. Many times I've had to count down the lines to determine where the student is on the report, and then go to the bottom of the report to scroll across to see what they still need to complete. When I reach the far right I then have to count down the rows to assure I've got the right person.
It's somewhat easier if I pull out a small number of student, for example last name beginning with "A", but if the name begins with "S" it becomes a lot harder as there are so many of them.
Just a suggestion - thank you for all the work you do, and the many improvements you've already made.
