Thank you for your comments.
However I think that this is a very useful feature especially for those who value the information in the leaflet. To me, just been able to have access to the back cover will be a major advance since there you have very useful information that is not in the cover.
I guess that, especially for classical, jazz and world music fans, this is an indispensable feature. So I would encourage the development team to consider this.
It would be, from my point of view, a major improvement in the way people can enjoy a musical work (an album, or a symphony, or a Indian raga), and not just a massive collection of individual song. I believe that this is one of the aspects that makes the different between music as entertainment (absolute fine with me) or as a cultural en artistic work.
