Back to KSP, looking for a specific mod

[Barbouze]

Hi!

I'm back playing KSP (last time was a long time ago, something like 0.22). Anyway, I'm looking for a mod that would allow me to create custom groups of parts or hide specific ones in the VAB/SPH. This way I could create a restricted set of stock parts that would be useful to explain KSP to my buddies and initiate them to basic rocketry, in sandbox mode. Is there a mod that already does this or a way to edit KSP files to get this?

Copy your install to a different folder, delete all the parts you don't want. KSP needs one command part to start up, iirc ( not done a completely empty install for a while ). Might not even need any parts now.

I believe you can make custom tabs in the part selector now. (I can't check because I'm still playing ver 0.25)

Thanks to both of you, I didn't see the "Add custom category" in the new part selector. If it's too annoying to use, I'll go to edit the files.
