New tab menu

First of all, as lots of players might already know, the old tab menu got removed a long time ago due to some Minecraft updates. Secondly and unfortunately, I can't find threads or screenshots explaining its system and how it was made. In short, owing to this menu, there were two separated lists of players from each team. For example on the left-hand side the blue team, and on right-hand side the red team. Moreover, on free-for-all or gungame, the player with the most kills was shown and how many kills this latter had.

You can simply check out the CTF's tab menu in order to understand what the old War one looked like. And having an organized tab menu allows players to notice whom a player plays with and what team he is in. However, I would like to see some improvements concerning the tab menu which I hope will be added to War 2.0:

What I already said above, such as two separated lists, and on ffa or gungame, the player with the most kills is shown and how many kills this latter currently has. Besides these lists, next to each player's name, there will be the player's current score for each game (kills, deaths and ratio). Accordingly, a scoreboard will be set up depending on of course each player's score. And it will be reset once the game ended.
