sorry i couldnt find the catrgoty for minecraft feedback website

when i want to write downs something in minecraft feedback website i barely find out where and when i finally do and i write it and upload it after a while i find it nowhere disapired not existing.
on the resent snapshot there is a new block right? the "respawn anchor"
it would be realy good if it was filled up with glowstone with dispensors or hoppers i would say that in feedback website but i have problems with it
