Here you can see a list of all projects on the current site and information about them. Projects that belong under a certain group are only displayed when this interface is accessed on the CMS Desk -> Tools -> Groups -> … Edit Group … -> Projects tab of the given group.
You can manage the projects in the list using the appropriate icon on the left side: Edit () or Delete ().
New projects can be created by using the New project link.
If there is a large amount of displayed projects, you can filter them by their name using the filter above the list.
