Heat Map Click Rate Segmentation
Add a selection tool to the click heatmap that lets users draw/box-select a region of the page (e.g., a product grid, nav bar, or hero banner). Once selected, the element list and click percentages recalculate so each element's percentage reflects its share of clicks within the selected region only, rather than as a percentage of total page clicks. This would let users answer questions like "within our product grid, which item gets the most clicks?" without that signal being diluted by high-traffic elements elsewhere on the page (e.g., header nav, footer links).
