Javascript Bookmarklet to filter & adjust amazon seller "manage inventory" table

Looking for a keen javascript developer to build a small bookmarklet (Chrome) to perform the following tasks: - cycle through all visible products on the amazon seller central "Manage inventory" page - hide all elements (child-products of variants AND stand-alone products) that don't have an "Active" status - count the remaining "Active" child elements for each variant-parent, rewrite the parent from "Variations (n)" to "Variations (m)" where n is the original number of variations (including all statuses) and m is the number of "Active" variations belonging to the current parent - hide all parent rows which do not have any "Active" variation children left We already have a partly running bookmarklet, however the jQuery available on the Amazon SellerCentral Manage Inventory page does not feature the .nextUntil() concept. Therefore we need a workaround for his piece. Here is the partly operation code (note: based on German version of the inventory management page, replace "Varianten" by "Variations" for the english version): $('.myTable > tbody > tr').not('*:contains("Active"), *:contains("Varianten")').css('display', 'none'); $('.mt-variations-row-parent').each((index, el) => $(el).find("td[data-column='status']").append(`Varianten (${$(el).nextUntil(":not(.mt-variations-row-child)").length})`) ); $('.mt-variations-row-parent:contains("Varianten (0)")').toggle();
