I think theres a settings option for 'no hud' ive done this a couple times in the tower for a screen shot of my guy. Never tried to use that settings for gameplay though since I never saw the practicality of it, so i cant comment on if its effective outside of the tower, still if players think it would be a used featured then sure go for it, it does no harm to me so why not. Although, i would feel like its not really the biggest of lacking features to get annoyed over.
