User:Hoo man/smartUndo.js

 /*
 * [[m:user:Hoo man]]; Version 1.2.0; 2012年06月10日;
 * Provides smart undo (automatic undo of many changes)
 * Requires rollback permissions (the script needs it to find pages which have undoable edits)
 * Tested in IE and FF with vector and monobook, uses my (Hoo man) wiki tools (functions.js)
 *
 * DO NOT COPY AND PASTE, instead use:

 //Smart undo, by [[m:user:Hoo man]]
 mw.loader.load('//meta.wikimedia.org/w/index.php?title=User:Hoo_man/smartUndo.js&action=raw&ctype=text/javascript');
