I think it would be great to have the ability to mark/bookmark where you are in a certain mp3 so that you can go back there in the future. I listen to a bunch of podcasts and audiobooks, many have multiple mp3s. I want to mark where I am in one mp3 file and then go to another audiobook, listen to it, mark where I am, then go back to where I was in the previous audiobook. Anyone want this functionality as well? It'd be a huge help. (Also, it would have to remember to play all of the subsequent mp3s of that specific audiobook associated with the bookmark)
