Great HUD, thanks for putting in the time and sharing it with all of us. I like the clean simple style and minimalist nature. I do have a couple of suggestions.
1. The spec HUD could use coloring; I know people have mentioned this. However, have you seen the HUD VanillaTV uses. Their spec HUD is excellent and has team and death coloring.
2. On high res screens, the text in charge bars can be hard to read. Is it possible to make the bars and text taller or bold the font.
3. The metal indicator for the engy seems awkwardly placed. My suggestion would be to put in between the health and ammo with its own icon.
4. Is there a way to change the ammo color when you are low on ammo.
5. The CTF indicators overlap and can be hard to see.
Also, is there a way to customize the height of the health and ammo, so I could move it lower on the screen, just personal preference. Finally, is there a way to dynamically change scoreboards while in game. Otherwise, its a fabulous HUD and I enjoy using it every time I play.
