Would be really cool to add functionality of hiding armor items so that they wouldn't show or to change the appearance of the item completely. Basically like the functionality in Assassin's creed Odyssey. Don't think this will be hard to implement.

Is this change\improvement is considered by Dev team?

If you ask on CDPR's Cyberpunk forum (the one on the CDPR website) they might see it, as for GOG I'm not sure. Some games also have the option of hiding helmets, that's probably more typical than hiding armor in general: V's "armor" is practically all the clothes, so what would hiding armor really mean? :-) The Emperor's New Armor.

Basically the functionality of a mod True Hidden Everything (on Nexus)
