Filter game list by system

[Dectoplays]

Hello there,

Running recalbox 9.1 on rpi3. great work from the debs. I'm still learning a lot.

I was expecting to be able to filter the game list easy by system through a menu option, like in retrobat. Any looking for this feature too? Any ideas how to do that? Or is there an open issue or feature request (I couldn't find so far on github?

Cheers,
Marcus
