 * Hello,
    First of all, I would like to say the plugin is very good. There are 
   some issues which are not unexpected to exist in the first versions. 🙂
 * The plugin is with clean code which does not rise notices and warnings which 
   is good (at least I dont see them), except on the newer version of PHP where 
   static routines should be explicitly defined as such, like in the other programming
   languages.
 * The issues I have encountered are in: **/includes/classes/ssp_skin.php**
 * The following methods should be **declared as static**, otherwise new versions
   will rise:
 * > Strict standards: Non-static method SSP_SKIN::_method_ should not be called
   > statically, assuming $this from incompatible context
 * Those methods are:
    - SSP_SKIN::setup_slider()
    - SSP_SKIN::set_active_skin()
    - SSP_SKIN::is_default_skin()
    - SSP_SKIN::get_skin_path()
 * I would suggest to add access modifiers as well:
    `public static function ...`
 * No matter PHP default is public, in most languages it is private. I would not
   be surprised if in future such change appear. Also it improves readability. 🙂
 * It is WP and plugin version independent.
