I'm experienced with many "mainstream" mods: say a hundred of different kinds. I'm new to this mod, and I find it a very good one. Actually I heard about it months ago, but it was dismissed by me because of the modest downloaded times. Now I've played it and I would say It's complete in itself and feels elegant. It can be compared to AAI Industry but is better (only that Xander does not support Space Exploration, which requires AAI installed). Maybe the intro here on this mod page is too concise to be able to get people realize its well-seasoned complexity. Also, the photos attached in the intro does not show what's interesting: some are too zoomed out, and for others, it's weird to present a base layout when it's a mod about new materials and intermediates. New buildings and their inter-structures should be shown large and clearly. Maybe a FNEI table of all materials tells much more. And the fact that this mod is as rich and complete as other "overhauls", and their comparisons, should be made clearer in the description rather than vague speeches as of now (e.g. "the mod has new ores for new metals, detailed refining processes, complex sequences of intermediate parts," blablabla - this is talking of, rather than talking about, the contents of this mod). I understand that this intro was written long ago, but a revision may do good to everyone. By some tweaks as such I think the download times have the potential to go up, maybe even multiply, because this mod is no less than its competitors - whose download times generally go up to 10k+ or even 100k+.
