Here's my thoughts:

- What if there is just no icon at all for spectators? They have grey names in the scoreboard and in chat. This communicates more than enough that this player is inactive. Whether or not they are spectating is not so important, whether they are part of the game is. A golden S or eyeballs don't really communicate that a whole lot better, it really just clutters the screen by communicating the same thing twice. And while we're at it, it should be good to also remove the roast 0 and the red death 0 scores from anyone that is spectating.

- I tried the green back panel, but it just looks ugly. I can't really go explain it into detail either since it's subjective, but translucent backpanels without any canvas edge or pattern look very cheap to me. Also some characters like 'y' clip through the translucency. Also, like Kev I didn't notice the backpanel at first since it's behind the text/icons you would be looking for. It doesn't do a good job at communicating information to the player and what that information is. I think for the admin I suggest to draw a small green cog icon instead of the green A, and make it only visible at a double f9 press instead of a single one.

- I don't like that the flag icon exists in both the left side and right side of the player name. Was this not consistently on the right before?

- For further clutter removal, remove the '+' icon whenever server has /plusonly on.
