If P4 allow users to add some text base information on their workspace then it will help them in various ways.
1. If i have worked on project one year ago and it needs certain information to be added. (Files sometimes not allowed in structure)
2. Some critical information to be shared with other users also for same project. (I am not sure other users has same area of working or not but i am sharing my views.)
3. Text will be stored on server so i do not need to worry about loosing information in future.
