So I just downloaded this and loaded it up in a sandbox save for testing, and noticed something. The Resource Mining and Processing tab was empty. Curious, and a little confused, I decided to look around in the configs. It was there that I noticed the Resource Extractors (Drills.cfg) and Resource Processors (ResourceProcessor.cfg) subtabs were set for all the various mod tabs and Resource Storage and Processing. I added Resource Mining and Processing to the start of the list, loaded KSP back up, and found the subtabs there like I assume they should be. Just thought I should point that out. It seems like an easy thing to miss. BTW: tabs refers to the main filers and subtabs refers to the subcategories on those.
