It gives: 
Cost Index, Flight Times, NOTAMS, Fuel (needs to be tweaked). 
What i hope to add: 
Weather Details, Step Climbs, Gates numbers, GCMap integration (Like simbrief) with the current plan and winds. 
I also hope to have the pdf exporter working soon. 
And for your information, we have the Tab-able area like you are suggesting:

MY QUESTION TO ALL OF YOU... 
Would anyone be interested in assisting me with the development of this "payware" system? 
Thanks!
