great app, the only disadvantage is that the sticky add to cart also becomes visible on the side menu of the shopping cart, causing the checkout button at the back to be hidden, which makes for an unpleasant shopping experience for the customer

Great app! The primary qualifications for adding a sticky add-to-cart widget to our site was that it must be fully-featured, lightweight, and not add any unnecessary code. This app meets all those requirements and, for the time being at least, is free! Highly recommend! Features I would like to see in the future include: - The ability to change the z-index in the GUI to manage whether the bar shows up in front of or behind other elements like cart drawers and popups. We managed this with some CSS, but built-in functionality would be nice. - The ability to change button shape/border radius, particular trendy pill shapes. - The option to display a color preview rather than color name text. - More granular font/typeface adjustments, particularly letter spacing and bold/italics. - Translucent or invisible background colors. The bar would look really slick with a translucent frosted glass effect. - Transitions when the bar appears and disappears - either sliding up and down or phasing in and out.
