If you are concerned with the amount of space taken up by the “D2L News” and the “Role Switch” in the left-hand column of the Course Home page — we have good news!
First, the students do NOT see the same width column on the left, because they do not see the “Role Switch” tool.
Second, instructors can make the column narrow by simply closing or minimizing the “Role Switch” box. Just click on the double-arrows icon on the right side of the title bar! See below for a screen shot.
