// LinkedIn recruiter search results highlighter.
// Paste into your browser's JavaScript console.
// 
// Features:
// - Auto-expand experience items
// - Color experience items based on duration (red if less than 1 year, green if 2y+, etc)
// - Strike-through experience items containing certain keywords
// - Record profiles already seen in search results and hide them in subsequent searches (to enable, set config variable to true below)
//
// If you make improvements, feel free to reach out and I can merge them. <aurelien.gasser at gmail.com>
// The is quick and dirty, please don't judge me 😅
