Custom user interface for widescreen monitor

I play now on a full hd widescreen monitor. It’s nice, but everything is soooooo small.

What should I change in which XML to increase the name tags above chars heads?

Is it possible to increase the size of the icons?

u can change size of numbers and names i guess,but all icons will be the same,only way is to draw it urself)

most icons have a max resolution of 64x64 pix before they get stretched (and ugly).

I found the XML for the nametags. Its 3dtext and 3dtext_small in fonts.xml.
