When the Maple Programming feature is disabled, all its plug-ins will be disabled also. They are still available on disk, and they can be enabled at any time in the future. To physically remove the feature and its plug-ins, you will have to manually remove the feature from the Eclipse/features directory and its plug-ins from the Eclipse/plug-ins directory. We advise extreme caution here. Remove the wrong ones, and you may have quite some trouble restoring your Eclipse to a stable state. Unless you care a lot about hard disk use, we recommend leaving the plug-ins where they are.
