How do I add custom part groups?

[Trexation]

I am aware of the sub groups tab, where you can create custom groups, but find them annoying as they do not transfer from save to save, and for various other reasons.

In [ksp-win] -> [GameData] -> [squad] -> [Parts] -> [ Aero] -> [Airbrake] -> [Airbrake.config]

I opened it (with notepad) and found this.

What I am looking to do in short is add a new category. If I change this pre-defined category to something other than a predefined category, the part vanishes (and re-appears when I change the category back).

by predefined category I mean

- Aero

- FuelTank

- Engine

- Utility

- Science

- (etc)

Thanks for any help!

Yes, I'd like that, too.

I believe that what you (and I) want can only be handled by having a mod. The "custom groups" feature I find totally useless, for a variety of reasons:

- Doesn't transfer from save to save.

- Is accessible only via the "detailed" view, which is cluttery and (except for subassemblies) useless to me. I hate it and therefore never use it unless I need to work with subassemblies, in which chase I have no choice.

- Other UI ugliness around the detailed design.

So I believe you're pretty much just out of luck, unless you either author a mod or else find a mod that does what you want.

I believe this will allow you to create custom editor categories without writing C# code: http://forum.kerbalspaceprogram.com/threads/104231-1-0-x-Filter-Extensions-2-2-2-(Jun-2)

Ok, thanks I will check this out!

Edit: It does subdivide the categories!

Notably it does not subdivide the mk2 and mk3 system into their own groups.

Help others who see this post know if the mod works or not.

That's because the default setup is to keep the stock categories and add a few helpful new ones. You can go into the files and create your own setup with a bit of effort

For example, a Module Manager patch adding all parts that use the Mk2 and Mk3 profiles to their own tab at the end of that list (Note: the Mk'x' subcategory is already defined, hence why there is no part parameters involved)

@CATEGORY[Filter?by?Function]
{
  @SUBCATEGORIES
  {
    list = Mk 2 [2.5 x 1.5 m]
    list = Mk 3 [3.3 x 3.8 m]
  }
}
