The light greyblue linked record background in the List View on Interfaces makes me sad.
Maybe make the grey take up the whole field, like a Large view of a Single Select field? Or maybe just transparent? I think something different would really help with the wonderful dropdown selection window.
It takes out the sadness of the dreary grey and replaces it with the joy of not-grey.
Look at that grey and tell me it doesn't make you sad. If it makes you sad, you're the target audience.
On a more serious note, I totally get that this is unlikely, as it's probably more a UI consistency thing, but by golly I resist with every fiber of my being using linked record fields on List View because of how they look.
