Hiding answers in the assignment (tehtävä) widget

When using Howspace in teaching it is not always okay for students to see each other's answers for assignments. Teacher often wants to show stuff for everyone from a big screen. It's problematic that then some of the answers are visible, and teacher can't show the part of page where the answers can be seen by others.

For superchat that is not a problem,, since you have to click a button to show all the answers. (It would be convenient to have a hide-button as well though!) But for assignment widget the answers cannot be hidden. It would be great to have the same show-button as in superchat!
