Wishlist plugin

Hi there, i am looking at buying the wishlists plugin but i have a few questions first as your demo doesnt work and the documentation is not clear.

where do i find the ID

do i need the pro version to select the settings? because it doesnt allow me to select any

i cannot add any wishlists, does the pro version allow for this?

does it create profiles per user?

how do i add the button to elements?
