The project page layout can be changed between a list view and a card view by using the drop down menu at the right of the navigation panel.
The default can be set under
Settings > User Settings and choose either list or card view from the drop down. Press save at the bottom of the page and your preferences will be updated.
The list view will show the project groups first and then any un-grouped projects are shown in a list at the bottom of the page.
The card view will show all projects as separate cards, these are colour coded to show the status of the project at a quick glance. The projects can be filtered into their user defined groups by using the main navigation to the left of the screen.
