Our school just transitioned to PowerTeacher Pro, and there is one thing that really aggravates me--the score sheet. On the old gradebook, the score sheet allowed you to easily scroll left to right and back again. This allowed you to see the entire scoresheet quickly and easily.
On Pro, you have to click the blue arrow as if you are turning a new page, and it's very inconvenient.
You can adjust the number of columns on the scoresheet by entering a value into the Columns/Page box underneath the sheet and hitting the Enter key. A scroll bar will appear at the bottom so that the scoresheet will function like you are requesting.
