occasionally i'll start a book, put it in my "reading" list, track progress, then for whatever reason stall the book. i don't want to have my "reading" list cluttered with titles that i'm not currently actively reading, so i move the titles back to "to read". however, doing that then erases all my previous dates and progress. it would be great if this could be preserved somehow for when i pick the book up again in future. or perhaps there could be another list called "stalled" or "on hold" where the progress could be retained, if adding the tracking progress capability to "to read" is too troublesome in the back end.
