[REQUEST] Option to reduce HUD opacity (like CS2's option)

[Void48]

This would be especially useful for people with OLED monitors. These have become much more common these days, and I would like to reduce the risk of burn-in from static HUD elements. Please consider adding an option to reduce the HUD opacity.

If this is out of scope for this project, please at least let me know how I'd be able to change the HUD opacity myself. Thanks!
