// @version       1.4
// ==/UserScript==
// improvements in 1.4:
//  - added @grant
//  - support overlay for mediawikis
// improvements over version 1.2:
//  - added: https://*.wikipedia.org/*
// improvements over version 1.1:
//  - support Chrome (Thanks to Ashok Koyi for sending me a patch)
//  - The search box is only enabled when clicking the top area.
//    This avoids some issues, because disabling the search box does
//    not recover the previous state accurately.
