Further edit as this plugin insisted on overwriting the download and plugin rem***l buttons and replacing them with the sort buttons.
i didnt like this,so now the original buttons remain and pluginsort can only be accessed by pressing the menu button once you have your plugin list displayed.
much better for users i think.
as usual extract and ftp to /usr/lib/enigma2/python/Plugins/Extensions/
send over pluginsort and chmod the folder to 755 and also the contents to 755 then restart enigma2
