I think the problems doesn't stem from using actions (which memory footprint
is rather small, but from storing the resulting DOM for undo). If you have a
bitmap editing program, with a document of say, 10MB uncompressed, and you
store the last applied actions, you have to store 10MB x n undo steps. This
becomes cumbersome.
But this doesn't apply to me, but to the actions itself. Are currentyl
backups of the DOM used?

You still could limit the actions to 30 actions. My idea just allows that
these 30 actions haven't to be done in the same session...
