As admins, the "undo" button is replaced by a "rollabck" button, the same Uskok had been using.

That button allows to undo "vandalism", unneeded or wrong edits by only pushing a button, but it doesn't allow to edit the summary of the edit, it simply undoes all the edits done by the last editor to the versión of the second to last editor.
