Trese Brothers Games (Star Traders: Frontiers and more)

I think the quantum leap in visuals from the previous games (as I remember them) makes them much more sellable with screenshots. It looks so much better. Is there a manual hidden somewhere? I tried it yesterday but could not figure out anything. What do all these symbols and icons mean, what are stats for what do skills do, why is the level of my credit important etc. I neither have the time nor inclination to figure this all out by myself right now. Never did to be honest, always have been an avid manual reader. So, anything like this out there? The game could use a proper tutorial or at least informative mousover popups for things.
