Mac OS X has a simple method for managing trashed items: The user selects a file to be deleted, sends it to the trash, and then empties the trash. The only additional feature built into OS X is the option to securely empty the trash, where the system will overwrite the file several times to ensure the magnetic patterns on the drive representing the file get altered enough that it is virtually impossible to recover them.
This simplicity can be quite limiting because it forces you to use the trash only as a temporary storage space for ALL enclosed items before they're permanently removed. There is no way to customize this behavior, but many people have inquired about being able to easily remove one or two items without removing the rest, essentially wishing to enable more flexibility in the default trash behavior.
