Slides without titles currently don't show up on the outline. @jjallaire had mentioned that this worked in v0.2.340, so title-less slides not showing up in the outline might be a regression. I think we had discussed that a title would be constructed for them based on the initial text the slide can find and put something like "Slide 3" if not.
