I would love to have quicker access to reading journal entries for read books. Right now I have to pull up the book, select "view/edit read history" and then "view journal entries." If the full reading journal log is able to be filtered by my notes only (as mentioned elsewhere), that would also help.

I'd also love to be able to go back and add additional reading journal notes after I've finished the book - I often have to make do with approx % markers to add quotes etc.
