Deleting completed projects
When you're finished with a project, you can delete it forever. When you have the project open, simply click the top right of the project window and select "Delete."
Here's a hot tip: If you want to have access to the project later on, you can simply close it rather than deleting it entirely. Go into the project tab under Details. Under the project description at the bottom, you can determine whether the project is open. Switch "Yes" to "No" and you're all set.
