Way to display expanded field description on workspace

Summary

Or way to display help information for a field

Content

We have some very busy workspaces showing user input to a number of questions. To maximise information on each workspace, which are already on separate tabs, the field descriptions are short. The field descriptions represent the question that the user answered eg.' What three goals will you set yourself this week?' would maybe just be 'goals' which easy enough but some of the questions are more complex. Ideally it would be great if we could hover over or click on a field and see what question the user was asked in full. as a pop-up or overlay, without taking up any extra workspace space.
