Thanks for sharing with me the View > Print! I did not notice that, and that solves most of my needs.
I really like this site, and can see myself putting a good amount of time into importing my collection, creating decks, etc. With that type of an investment of time, I just like to be able to easily get my data out. I've lost time before putting a ton of information into sites to only have something happen, and its nice to know I can protect myself from that.
I'm also just getting back into Magic, and imagine there might be other tools I use besides deckbox. Deckbox has the great ability to export the collection, which is nice - I imagine I may find tools that could benefit from being able to import a deck (or decks). But I imagine the format you pointed out from View -> Print will work well in those cases (or at least be easy enough to transform).
