When marking a book as Want to Read, there's no way to see from the UI what date that occurred on. My current workaround is to add every title to a list which does generate a journal entry, but this seems like an unnecessary extra step. (Particularly when adding to a large list often fails.)

One of my most important tracking metrics is 'how long has this been on my tbr' and there's no easy way to see that. If not with a journal entry, then with another visible field.
