Make the target selectors more obvious

The idea is to make target selectors easier to use (both in java and bedrock) because currently, the target selectors are kinda weird, i mean, does anyone know what rxm means? They should make it easier, lets say you wanna detect where a player is facing, instead of doing weird stuff, just type @a[facing=<-n, +n, -w, +w, -s, +s, -e, +e>], see? And to make it better, there should be one called @a[facingcoordinate=], i just think mojang should do this, it's gonna help command block beginners or pro's (like myself) do things easier, instead of doing magic matrix stuff, just type [facing=]
