Default [Q] Swicthing between the Status bars

OK when you pull down your status bar, you can sometimes (on some roms) swipe to the right or left on a blank spot and it will switch over to the Quick Tiles pulldown.

I have tried looking everywhere that lets me turn it on, or a Xposed module, etc.

I have no idea what it is really called. Anyone know/can help?

Roms that have it. (Harmony) (Paranoid SaberDroid + REMIX)

Roms that don't

Stock Roms, etc.

Thanks again for any info as this is bugging me.
