Not to be confused with notes or keynotes. A very simple pop up text notation tool that is specific to what ever view you are in that you can keep project notes as you work. It does not need to have any fancy text formating as it is just for basic notations. Specific to each view in that each view could have its own notations - I think this is important. Although I do not use worksets, I could see this being very usefull on multi user projects. I have used other software with basic notation tools and find it very usefull.
