I second this, also if this file is created AND there is a general consensus about its content (it being correct, it doesn't create double entries, etc) it might just be a good idea to include it from the very start. This would make the app complete (or at least posses the latest official content) directly from the beginning.

And indeed, if there is a "simple" (or at least some) way to view, alter and create the .dd5 files on desktop...
