Cosmetic Store Pro – Need help changing some items (not in the documentation)

1- On the slides, I want to remove the slider icon. I see where I can change it but there’s no “remove” option.
2- I want to change the color of the top Header (by default is black) where my logo is located. Can this be changed?
3- On the very bottom of the Footer section: How do I change the hyperlink “Cosmetic Pro” after the copyright? The widget only allows changing the word copyright and the year.
I have emailed Support but they have not helped.
