The project page is accessible via the main menu under the Editing tab. It contains a section where you can add a new project with a choice of two types (Several more will be added in the near future.).
The project list shows a paged and sortable subset of your projects. Depending on the type various actions are available to permit editing and testing of your projects.
Columns are sortable and filterable. The Map ID column contains the id of that project, which is used with the API app to set the project.
