Then these are your experiences with "your" users... but for me an undo is
annoying (and even quite unuseable) which doesn't protect me against
accidentally "undoing some undos" (i.e. with current Emacs-undo i get no
information from Emacs that my undo-action is not really an undo but a redo
of a previous undo - if you understand what i try to say ;-)
And when undoing some steps i often reach a point where i do not know exactly
where i'm in the undo-chain - whereas with redo.el i exactly know when i have
undone all and when there is nothing more to undo - IMHO much more intuitive...
but maybe it#s a matter of taste...
