The tab |settings_tool| :guilabel:`Settings` allows for the customization
of :guilabel:`SCP`.

The :guilabel:`Simplified interface` is loaded after the first installation of
the plugin.
The :guilabel:`Complete interface` can be loaded from the settings in the
:ref:`SCP_menu`, by deselecting :guilabel:`Simplified interface` and
restarting QGIS.

    * - Tool symbol and name

    * - :guilabel:`Available RAM (MB)` |input_number| |registry_save|
      - set the available RAM (in MB) that is used during the processes in
        order to improve the :guilabel:`SCP` performance; this value should be
        half of the system RAM (e.g. 2048MB if system has 4GB of RAM)
    * - :guilabel:`CPU threads` |input_number| |registry_save|
      - set the number of threads available for processing; it is recommended
        to set a value lower than the maximum number of system threads (e.g.
        if the system has 4 available threads set the value 3)
    * - |radiobutton| :guilabel:`Simplified interface` |registry_save|
      - if active, use the :guilabel:`Simplified interface`, otherwise use the
