Yes, I heavily rely on a unique Media Deck, for three reasons:
- several decks make use of the same media (e.g. chinese-french / french-chinese (*));
- several decks make use different kind of media (e.g. regions of china = maps (standalone) + sounds (from vocabulary decks);
- all the media are in the same place, which is far more easy to deal with (update, browsing, corrections, etc.)
Ernie, please don't remove such a "power-user" feature. Downgrading is a pain on the iPhone.
Jason, I am not sure what you mean with "rename the files as vocab". I do have a rather complex naming scheme, i.e., generating a md5 hash for each sound file:
0a35e149dbbb2d10d744bf675c7744b1.m4a
0a60b24f661e4881c6baac0979c615e4.m4a
0a60c7a1be58c68b6f78f347fad2a75d.m4a
There are several advantages to this, but I could not encourage you in this way if you're not yourself a programmer

(*) Reverting the order is simply not an option for me, due to the complexity of my cards. Symmetric decks != same sides.
