Replying to [comment:4 fredck]:
> Also, I've noted the new "serializable" feature for the bookmarks. While
the intention is good, it's not a good thing for us in this case. The undo
system executes several times during the document lifetime. Using the
current bookmarks, you are constantly adding nodes to the DOM.
>
I don't quite understand the last point since the bookmark nodes will also
be removed just like ordinary bookmark in
''CKEDITOR.dom.range::moveToBookmark''.[[BR]]
> The above is not necessary as a undo snapshot is "stable". It contains a
DOM tree and the selection position can safely be reconstructed by using
the node counting system used in V2 (CreateBookmark2). So, I would do a
step back an use that non intrusive bookmark system again.
>
My original consideration on the unobtrusive bookmark (CreateBookmark2) is
that it might be weaker than current one from PF.
