Allow addons to apply per-quantity or per-order
Currently, addons get multiplied by the quantity selected for the product. Would be great if there was an option to specify if addon prices should apply per-quantity, or only once regardless of quantity.

You can find this functionality in this plugin https://codecanyon.net/item/woocommerce-product-addons-custom-product-options-plugin/20810733 . It provides you option to multiply addons/options with quantity of products or price it once, no matter whats the product or order quantity.
