Tonight I noticed that there's an addition to the choices on the 'My Bookshelf' dropdown menu: Notes/Reviews. It shows notes newest to oldest on recipes and books that are on my Bookshelf.
Excellent!
As it happens, I added a Note to a book today, and it was the one at the top of the list, so for a moment I thought this was a list of just my Notes, newest to oldest, the same as looking at my profile. Then I realized it's all Notes pertaining to my Bookshelf holdings, a tailored version of the big Notes feed in the Library menus.
Another encouraging aspect was that this note of mine at the top of the list was one I'd made private, and I was able to see it. To my delight, this is now true in the profile, too. Yay!
However, it gave me a slight turn because there was no little yellow lock symbol to indicate 'private note'; I was reassured to see that the 'private' symbol was there when I went to the Notes for that book. It would be ideal if private notes in My Bookshelf and my profile would still display the lock symbol as they do when viewed from a single recipe or book page. I'm assuming this feature/bug fix is still in process, along with others, so maybe that's the plan in any case.
Just wanted to cheer you on; thanks!
