A typed input object -- like a text box -- would be nice for the Journal/Reader annotation. If I were paying for development I'd add structured drawing to Journal. Something similar to Visio or OpenOffice.org Draw, but a little more simple.
Also, using hand writing recognition to turn personal scribbling into computer text would be nifty too. There's another thread in the Features section about that.
