Add audiobook option to book info

Description of your request or bug report:

As mentioned in the other thread, it would be nice to have a way of recording if you listened to an audiobook (either accompanying reading or on its own) on the book info page.

Trello link:

joining in on the request, I was just now looking to see if there was a request on the matter :smiley:
for now I’ll probably do a [total page number] divided by [total track number] to track my listening I guess?
but having an actual way to V the tracks I listened to like I do with page numbers normally will be nice/even just a general V when I finish it as audio rather then directly reading it

I just do current location / overall minutes and then enter my percent finished, although if the tracks are fairly consistent for number of minutes I have done 1/tracks (ie, 10 tracks = each chapter is 10%) and used that for percentage as a close-enough shorthand.

Necroing this thread to chime in that it’d be really nice to have native audiobook handling, i.e. that the progress tracker uses duration instead of percent. (This is partially an audible issue, but I have to calculate my percentage in a spreadsheet and then use that to track my Natively progress.. not super fun). But it is also a little weird that it’s reporting pages read and not time read, and also messes with my page stats.
