Better-looking UI/layout
I think the -entire- UI needs to be re-designed. Every UI element that has a font should have settings for font size/color. Every window/widget should be able to be moved/re-sized.
Anchors would be nice so we can choose which window pops up where instead of all on top of each other.
Scaling per ui part and not all at once. I like the icons small but then the chat window becomes too small to read
Sometimes I play with hiding my UI. the only time i turn it back on is to see how my health is. Maybe some more visible signs on the HP status might help (red flashes happen with me as soon as i take damage)
