Allow to disable Wifi? Probably via OLED screen menu?

[M-Reimer]

I'm wondering if there are more people that would enjoy being able to actually disable Wifi if not needed.

I could think of having this as an option in the OLED screen menu. This way no additional GPIO would be wasted just for a hardware switch.

I'm not that much into reconfiguring a scaler all the time. I did a basic configuration which does work well for my two consoles (SNES and N64) and for doing this I didn't even bother integrating the scaler into my home network and used the "built in access point" for this. Now, as I have the settings I like, I actually no longer need the access point to create additional noise in the wifi band. I would prefer to just switch off Wifi completely util I need it again.
