Yeah, this one was my very first PR: https://github.com/KSP-CKAN/CKAN/pull/2392
Actually a feature PR.
Love the description:
> Hey, I just thought of a little enhancement, and decided to create the PR myself.
> [...]
> I'm not that experienced at programming and furthermore this is my first commit on CKAN and I just copy-pasted together code which seemed to do the right things, after trying to get an overview of the code for some hours :D
> 
> Well, it worked after building, so yeah.
