I use many book tracking apps, including StoryGraph, and it would be great if you could have the option to opt into a more customizable style for indicating a books page count similar to that of Margins, where you can put in the duration of an audiobook and the total pages yourself as as the reader. This would be helpful for books that don’t include Roman numerals or if the user wants to add or exclude front or back matter contact. Right now the only option we have is to add a new addition, but it would be great if we could have the option to customers our own metrics or stats (pages/duration) for each book.
