I've tested Final Frontier current version: 0.7.5-933 with Kerbal Space Program v1.0.2.842 and it appears to be working - no other mods installed. However, the FF ribbon does appear over the icon on the right of the FF icon as seen in the top right of the image.
I like this, another reason for electricity use and perhaps a Science experiment where you would need to obtain some resources from other planets that are used in some of the experiments! Oooh, ALIEN TECHNONLY Techtree.
First off, excellent work Squad! Second, it would be great if all Science collected is recorded so that I know what areas I need to explore throughout each planet. Thanks and keep up the good work.
