Off hand feature for Minecraft bedrock and pocket

Hi mojang,

I am Minecraft pocket player . I don't understand.because some Java edition features not available in Minecraft pocket and bedrock.

Here the list 

                   1)off hand feature 

In Java edition,we can hold any items in offhand but this feature is opposite to bedrock and pocket,that is we only hold few item in offhand like arrow,rocket,totem and much less etc,.

Please mojang add this offhand feature to pocket and bedrock players.

                    2) advancement 

In Java,every world I create I got advancement.but in bedrock and pocket advancement box in the corner of the screen not available.but recipe unlocking is available.why mojang??????.we need : when I entered in my world I entered in nether, "we need to go deeper"advancement show in that world and I made full netherite Armor,"cover me with debris"advancement shown in that world.that advancement is made into message in chat.so mojang please also offer this advancement like Java for each world I create.

                       3) Dynamic light

You know the dynamic light feature mojang.please enable this dynamic light feature.

                         4)gui

Make the gui like java in bedrock and pocket 

                           5) health 

In Java , health regenerates very fast but in bedrock and pocket,1/2 heart per 4 seconds.

So make the regeneration of health in bedrock and pocket 

                           Please mojang enable voice chat feature also in mcpe and bedrock 

 thanks mojang,I waiting for your message
