Improving Lr for iPad with basic features

I love using my iPad for editing pictures but some features doesn’t exist on Lr for IPad and it is frustrating.

The main ones:

-being able to fusion 2 or 3 pictures with different exposure (bracketing)

-being able to duplicate a picture (easier visibility of different edition from a same picture)

-color label, available on Lr CC and classic

-curves copy and paste (being able to replicate the exact red curve on blue and green by example)

-point color tool available in Lr CC

thanks for reading theses suggestions
