RapidWeaver Stacks add-on info: The GetUp Stack button becomes visible when visitor scrolls or swipes down your page and provides an easy way to the top again.
Special features: You can style the button with 15 different icons, text or an image or logo of your own choice (png-file). Customize button background, text color, font-size, add opacity, make it square, rounded or round. Or make it spin on hover. Position it right, left or make to go full width at the bottom of the page.
You can even add two GetUp stacks at the same page… you probably don't want that – but why not show your logo as a scroll to the top button?
