I'm a bit crazy and I've decided to make my first app.  I spend 4 hours a day on trains and thought it would be a good use of my time.  Since I love SOASE, I thought it would be as good as anything to do.  However, I was curious what things people would like to see on an app for the game.  To clarify, I'm not making a SOASE replica game (not that good!), but rather a utility app.  I'm thinking things like research trees, ships database, etc.
So what is your feature wishlist for this?  Also, I'm curious if you think I should target it for tablets or phones (which you could use on tablets as well of course).
Thoughts?

P.S. - I'll probably start with iOS first
P.S.2 - It will probably take awhile!
P.S.3 - It will be free.
P.S.4 - I already made a research trees webpage which you can download here in the meantime.
