That is exactly what I meant. draft.of contains the original title of the
tiddler that is being edited; i.e. the name the tiddler had when you click
the edit button, even if you change the title during editing. draft.title
contains
the title that the tiddler should get after editing. When you just pressed
the edit button, this coincides with draft.of, because you haven't changed
the title yet, but when you do, draft.title updates.
Now I am not that familiar with TiddlyWikis editing lifecycle internals,
yet, but I presume that both are needed at the moment you save the tiddler.
You want to be able to reference the original tiddler, for example to
potentially delete it when you changed the title, or to write the new
values of the draft tiddler back to it if you didn't. Also, if you changed
the title, you of course need to be able to reference that, to actually
create the new tiddler.
