Looks very nice. Myself, I would prefer to see no sidebar to the upper left, and instead have my kills announced to me in the center of the screen as usual. After all, the scoreboard is very easily accessible. Maybe some modifications to that so it only shows the scores?
Just edit the CFG and enter the values you normally use for the hud blends, and change all of the binds to the key of your choice. (there's three, all must be the same)
