I was studying without a network connection on my ipod for about an hour and a half on the train the other day and eventually I started to review the same words over and over again. I realize that I need a network connection to add new words, but it doesn't seem like it should be too hard to have the device download an entire list's vocabulary and thus be able to add new words to my study-list even while offline, no? I'm just wondering if there are any plans for this to happen or if there are complications I am unaware of in regards to doing that, because I only ever study on the train, which never has a connection.
