Hello. I've found one utility "ImpExpGrpLO" by Patrick DIDIER, which can import groups from one mission file into another. It seeems OK, but it doesn't work under WinXP SP2 ("unhandled exception"), only under SP1. How this can be repaired? Any contacts of the author? Any other util with the same fun...

Great plugin! Thanks!
But fuel indication in per cent (%), IMHO, is not a good idea :(
Kilograms and pounds would be better.
