I love the display rules and they are very handy in both the normal detail views and on forms. In both situations, I sometimes have a "Title" or a "Title/Instructions" in my view/form that is a label for a block of fields that I will hide under certain conditions.
At the moment, there is no way to make the title / title-instructions show hide with it.
It could be in the list as "Title -> <Text of the Title Field>" when choosing what to show or hide with the display rules. Thanks for considering.
