[Java Parity] Advanced /Scoreboard Commands

     As a command block expert I have created many amazing minigames that I host for my friends, I, and the xbox minecraft community to enjoy through the group post feature. However, time and time again I hear the same suggestions being made to me on some improvements regarding some of my maps, but despite my attempts to find work-arounds to replicate some things that you can do in java, some thing are unreperable. I have to constantly remind people of the limitations of bedrock edition by saying that it wasn't possible to satisfy their demands on this version of minecraft and it's getting old now.

A particular map of mine is a kit pvp that took me years to make and it is my pride and joy, but I can't even prevent friendly fire between members on the same team!

A fix for all of this is the implementation of advanced scoreboards in the same way it is displayed on java edition:

1. First priority is scoreboard teams:

     This will allow team mates to easily be able to see, identify, and recognize everyone on their team and prevent them from killing their team mates accidentally and resulting in more unjust casualties.

2. Second priority is objective tracking scoreboards:

     Minecraft had to expand this list beyond just dummy scoreboards so that these scoreboards can track player health and other stats such as hitting other players to allow for better a better pvp experience that is much more coherent.

This will enhance all team based maps for all creaters for a better experience!
