I'm using a theme that provides an YARPP template plus child theme support. While customizing such a child theme of mine then, I noticed YARPP had switched back to the its non-templated output. I went to its options, I no theme template was shown, meaning YARPP isn't child/parent theme-aware.
The workaround was simple enough: copying the php file from the main theme to the child theme folder made it appear in YARPP's options. But it'd be very nice to have YARPP automatically recognize when a child theme is active and, if an YARPP template isn't available in it, checked with the parent whether it provides one then listing this one if its there.
