Keybind for turning off HUD or changing HUD opacity

The game is so beautiful, I usually make lots of screenshots while playing. But PC interface toggle is so frustrating (a player has to go through 2 settings windows to change HUD opacity) and after it a giant notification hangs on at the bottom of the screen for quite a long time.

That's why I personally prefer to play with UI completely turned off, but it's difficult sometimes, especially when I'm leveling a new toon and trying to find a quest objective.

I realize this is probably not the top issue on everyone's mind, but please, for the love of the Traveler, add a keybind for changing HUD opacity on PC or a special keybind to completely turn off UI. Or maybe a camera mode, as it was suggested many times on this sub.
