I am aware as is most people that its possible to assign images to the project folder icon via the web interface. However, there is a relativlty large amount of extra time used with finding a good image that best represents the contents of a folder. I was considering something similar to that of a icon which is made up of a selection of the most recent or most used files within the folder being used at the icon of the project folder. This would just allow for better navigation within the data panel and save a lot of time.
