ABOVE CODE SLOWS DOWN BACKEND!
I’m using nested Flexible Content fields and this function really slows down my backend when dealing with alot of fields. Also it slows down the Media-modal that comes up when you choose a picture for example.
It seems append is called to often? I can’t figure out why it slows down at the moment, i’m putting this on ice until i have more time.
Hopefully Elliot makes this functionality part of core!
