// @name         [AliExpress.com] Haka's Clean UI | Remove JUNK!
// @version      1.1
// @description  Reorder the listing page layout to make more sense.
// @match        https://www.aliexpress.com/*

// Motive:
// - AliExpress' UI is clunky, I probably wasted hours just scrolling a product page to find its information.
// - Sellers try to trick you with a 'fake' picture connected to the listing/description. Don't trust images, always check what is written, this helps you with that.
// Features:
// - Display correct initial picture and not the thumbnail, so that the price is correct.
// - Prefer text on product description, push images below.
// - Push additional product listings to the bottom of the page.
// - Product description and reviews splitscreen.
// - Resize unimportant things to become smaller.
