    Yes, the module is designed to evolve over time.

    settings via the standard NbPreferences API and ignores all other settings.

            What other NetBeans projects and modules does this one depend on?
            <hint>
            Depending on other NetBeans projects influnces the ability of
            users of your work to customize their own branded version of
            NetBeans by enabling and disabling some modules. Too
            much dependencies restrict this kind of customization. If that
            is your case, then you may want to split your functionality into
            pieces of autoload, eager and regular modules which can be
            enabled independently. Usually the answer to this question
            is generated from your <code>project.xml</code> file, but

        <question id="resources-preferences" when="final">
            Does your module uses preferences via Preferences API? Does your module use NbPreferences or
            or regular JDK Preferences ? Does it read, write or both ? 
            Does it share preferences with other modules ? If so, then why ?
            <hint>
                You may use
                    &lt;api type="export" group="preferences"
                    name="preference node name" category="private"&gt;
                    description of individual keys, where it is used, what it
                    influences, whether the module reads/write it, etc.
                    &lt;/api&gt;
                Due to XML ID restrictions, rather than /org/netbeans/modules/foo give the "name" as org.netbeans.modules.foo.
                Note that if you use NbPreferences this name will then be the same as the code name base of the module.
            </hint>

 <answer id="resources-preferences">

    Yes, using NbPreferences for its own settings. It does not share them.

            Does your module read any resources from layers? For what purpose?
            
            <hint>
            As this is some kind of intermodule dependency, it is a kind of API.
            Please describe it and classify according to

<!--
        <question id="security-grant" when="final">
            Does your code grant additional rights to some other code?
            <hint>Avoid using a class loader that adds extra
            permissions to loaded code unless really necessary.
            Also note that your API implementation
            can also expose unneeded permissions to enemy code by
            calling AccessController.doPrivileged().</hint>

            Does your functionality require modifications to the standard policy file?
            <hint>Your code might pass control to third-party code not
            coming from trusted domains. This could be code downloaded over the
            network or code coming from libraries that are not bundled
            with NetBeans. Which permissions need to be granted to which domains?</hint>
