This idea organizes projects with similar topics under "user-defined" group folders (i.e. "Politics," "Education," "Health," "Travel," etc.). However, creating groups is optional:

1. In the Lumo interface, one tab lists the groups and a second tab lists all projects, regardless of their group.

2. Groups can be created separately (empty folders). A group can also be created when a user creates a new project and assigns it to a group that doesn't already exist.

3. Projects can be create with/without specifying a group.

4. One, or more, projects can be moved from one group to another.

5. One, or more, groups can be selected for deletion. If they contain projects, the user is given fair warning.

6. Group folders can be sorted alphabetically.

7. Project folders can be sorted alphabetically.

8. The user can "search" for a particular project.

Thank you.
