On the hompages of both Contact and Project management you will find a list of the latest documents that have been added - by any user - to the system. As with Tasks drilling down to Company, Contact or Project level will refine the list to become particular to whatever you are looking at.
So you always see whatever else is going on and have quick and easy access to the documents most relevant to you.
And because all the documents are accessible through a web browser you can access them wherever and whenever you like.
