Sometimes it might be very useful to show just two, or three Projects in Dashboard or Calendar, instead of all or just one.
This article will show you how to.
For Dashboard
Go in Dashboard in the top menu to 'Select projects'.
Hover over it and find all the Projects that are selected and unselect.
By checking only the boxes of the Projects you want to see, you will will exclude others to show up in your Dashboard.
You can now work with only those Projects.
For Calendar
Go to Calendar. You will find the 'Manage' button in the menu on the top left.
Click on it to open the Calendar display.
From here you can select the Projects you want to see in Calendar View.
