Hello,

3. Sticky add to cart before price position please check screenshot https://prnt.sc/ou4png you can customize or find a developer who would it
7. Remove attribute watermark from product images https://prnt.sc/ou4r3j It is impossible.

You can create one HTML block and insert its shortcode into the Theme Settings. Before “Add to cart button” & After “Add to cart button” https://xtemos.com/docs/woodmart/html-blocks-2/#before_after
