An option for bigger icons for tired eyes or dissable people

I´m aware that the hud is big and has a lot of elements and I enjoy all of them and the posibilities they give me, but sometimes is hard for me to see or find a lot of the mini-icons at the top of the screen
maybe an option for doing them a bit bigger would be possible?
I already used the zoom, a lovely idea btw, at its max, but I still would be thankful for bigger icons for that.

And also, a color-coded option for the buttons at the bottom would be nice, since the demo, the hud has changed and I get lost very often trying to find the options I search.

thanks a lot for your hard work!
