Organize Imports
From FDT Documentation
During the course of writing code, either you will need to import an object into your class or unused imports will accumulate. Using Organize Imports, CMD+SHIFT+O (OSX) or CTRIL+SHIFT+O (Win) will both remove unused import statements and add any import statements your code needs. With our Main class active in the editor, use the Organize Imports key stoke to get rid of that unused 'Shape' import statement.
