The file name for a Feature should be the same as the Feature that the file contains. Example: Picking.feature
Feature Files that contain Scenarios meant to be imported into many other Features should be created in the Utilities directory within the Feature directory and the word "Utilities" should be included in the file name.
If a group of Features are related or dependent upon each other, the names should contain a common root within the name. For instance, a set of Features created to support an enhancement would all contain the enhancement within the name.
