I like to place the My Week page on a vertical monitor next to me while I work. However, when the window gets more narrow, the only row that collapses to accommodate the new viewport size is the task title. This means the content of the task is truncated with an ellipse.
A lot of screen real estate is used up by the “Hide” button next to each item and an empty column to the right of the table. Having these disappear when the window is narrow (or having the option to toggle them off) would leave more space for the most useful information on the My Week page. See my attachment for a screenshot of the behavior.
