It is possible to add a title through OmniOutliner. If you enter a outline title yourself in OmniOutliner that will be used for the title tag. However, the default of the file name is ignored. In OmniOutliner, show the title (View -> Show Outline Title -> Always) and you'll see a bubble tag with the file name. Edit that field and enter your own text, that will be used for the html title tag. I've logged a bug on this and we'll get it fixed.
