manque de commandes

Hello

Regarding the commands available in the game minecraft Windows 10, there is a lot missing for the map-makking. The /scoreboard does not have teams, for the objectives there is only the dummy criterion when creating a lens while there is supposed to be deathCount and many others (to create automatic kills or death counters. The /summon also lacks precision for example to create a villager with personalized exchanges. And there are still some, like getting a village-style entity to talk about in the chat or making sure that a block can only be applied to a specific block (e.g. a lever that can only be placed on a block of diamonds). Please correct/add this
