Looking for suggestions on what else to do with my Kodi

My setup
Raspberry Pi 3 B
– Flirc case
– 32gb flash
– Overclocked to Medium (900, 333, 450, 2)
– LibreELEC 7.0.2
– Kodi 16.1
(Powered by TV usb, so it turns on with TV)

Currently I am not using it much. It has some Chinese streams for my wife, and a few music albums on it. Eventally, when we move, I want to create a house wide media network.

I was thinking of loading a ROM program so I can play some old games.

Other than these, does anyone have any suggestions of interesting Add Ons?
