Code that you insert on this page could contain malicious content capable of compromising your account. If you import a script from another page with "importScript", "mw.loader.load", "iusc", or "lusc", take note that this causes you to dynamically load a remote script, which could be changed by others. Editors are responsible for all edits and actions they perform, including by scripts. User scripts are not centrally supported and may malfunction or become inoperable due to software changes. A guide to help you find broken scripts is available. If you are unsure whether code you are adding to this page is safe, you can ask at the appropriate village pump.

// NOTE: THIS SCRIPT IS NOT BEING MAINTAINED
//  mobileUndo 2.0.0, a script allowing reversion of edits on mobile.

//  Installation instructions at [[User:DannyS712/Undo]].
//  <doc>  This script basically connects an API endpoint to 
//         a mw-ui-destructive button which is added to the 
//         footer by using jQuery. Additional functionality 
//         includes changing the position of the thanks button
//         and the addition of a confirm dialog to the thank button,
//         to prevent mis-clicks due to both buttons being close 
//         to each other.
