I would love to see some simple DM tools.  They don't have to be super sophisticated in the beginning, but would be super helpful.  

I'm thinking 1) a simple monster card set.  Like Pick monsters from the manual and create small cards for them for combat tracking, 2) combat tracking and initiative order tables. -- could be really simple.  3) DM awards like treasure, gold, items etc in the form of either simple cards to better yet play item transfer, where the DM could just pass items into the players stash.

Thanks
