The projects view is the first view you see after you log in.
It allows you to do the following:
Create a new project
View all existing projects
View all data frames contained in the current project
View all models contained in the current project
Please note that the models contained in the current project will be automatically loaded into memory once you load a new project.
However, the data frames will not be automatically loaded. You can do so by clicking the load button or by using an appropriate call from the API.
