What are the *small* additions, that you want to see in GT7?

In reality, all non-editable liveries become editable with a few simple steps.

Apply the livery in GT Auto, save it, go back to "Load Style" and apply the now editable version from "My items". Then you can modify it as much as you like.
Is there any way to take someone else’s livery and use it as a base for your own livery, then save that and share it with others?

I’m working on a Porsche GT4RS livery but started by using someone else’s livery first. I’ve made tons of modifications and adjustments to make it more accurate, but once it is done the game will likely not let me share it because it will say it is someone else’s livery.

Is there any way to bypass that?

Not that I know of. I understand not sharing so you can't take credit for someone else's initial idea and design, but yeah...sometimes I change so much that I really would love to share it.
