Removing Elements from a Feature
In addition to adding to elements to feature you can all remove files that you do not want as part of a feature. To do this you simply select a file or folder from either the 'Incoming' or 'Outgoing Dependencies' panel, right click on it and select 'Mark as Processed'. A line will then be drawn through that file/folder. You can choose to not display all processed files and folders by de-selecting the 'Show Processed' icon, found on the top right of the panel.
