Jivelite and (hopefully) Screen Switcher Applet

Hello,
i used my Squeezebox-Touch for years but now i switched to a Raspberry 3 with pCP, Jivelite and 7'' display. This setting is a good replacement for my old touch but there is on thing i really miss.
It's the Screen Switcher Applet from Erland Isaksson. http://wiki.slimdevices.com/index.ph...witcher_applet
Sadly it is not listed in the Applet Installer.

Is there any chance to get this applet working in jivelite?
Maybe someone has a good idea.

Thanks
