When I create a new project, I give it a short but descriptive title. However, the title itself does not contain nearly enough space to describe the project. I need to add more details about the project somewhere as both a reminder to myself or to other people involved in the project to keep us all on track. In project management literature this might be described as the "Project Vision".

At the moment, I use a card to store this information but this is not a good use of that screen space or in keeping with the essential purpose of a card (i.e. it is not something to be worked on nor would it ever be moved through columns and finally completed).
