Blocks can be docked (minimized and moved to the extreme upper left to next to the UofM logo).
To learn more on docking and undocking blocks, you can also watch this short orientation video (approximately 45 seconds).
Docked blocks will appear on the extreme left side of the webpage, in a vertical bar.
To undock a block, mouse over the gray box along the left side of the page and click the icon with a grey arrow pointing to the right. The block will return to the original location.
