Disabling The Crosshairs Completely

[JoeyZero]

Hello everyone!
Formally casual FPS player here. Just wanted to drop a quick suggestion in the box - can we have an option (even something unlockable, like after you've completed all of the missions or something) to toggle or temporarily disable the crosshair or UI?

 

Roughly a week or two ago I glitched out and couldn't see any of my UI, including my crosshair. It kind of freaked me out at first, but I adapted to it, and it eventually just made me wish that this was intentional - for training purposes. I remember how much I improved in Halo (forever ago) thanks to 'blind mode' where the UI was disabled. I guess because it forced me to aim with the whole screen, rather than slowly developing tunnel vision around the crosshair.

 

Anyway, I'd very much like to see this or other difficulty-increasing features aside from 'Take your mods off' or 'Use an unranked frame'.
