Add the ability in the theme settings to choose what to display in the sticky add to cart on the product page (separately for desktop, separately for mobile)
Namely:
  • display buy now or add to cart button with quantity
  • whether to display the price (currently it is not displayed on mobile, which is not very good)
  • display add to wishlist button
  • display add to compare button
  • display a selection of options (after selection, show the price and the option to add the selected item to cart - currently it only works as a slide to the top of the product where these options are)
