"Special" Cards

[Alwiz79]

Hi Fuzzwah!
Thanks a lot for this great project!! My kids and I just love it!
I saw in your python code, that you have configured some "special" cards (to shuffle or to shut down e.g.).
My question is: how do I set up these cards ? Do I need to have a playlist named e.g. shuffle.m3u or shutdown.m3u?
Or how does it work ?
Also: since kodi has a command line API, shouldn't it be easier to swipe a card and then shuffle, or shut down, or set a timer (I tend to call these "parents functions" :-) )
Cheers!
