I noticed this yesterday, but an not sure if it is very recent, or simply is being rolled out slowly, or did I just miss it before ?
Anyway, on the matches listing page, each match has a note on the 'summary details' block, a note of basic dna details, - total number of CM shared, and across a given number of segments. There is also a compare logo, which when clicked, shows you a comparison of ethnic estimates (which can vary depending on whether the match or you have loaded the update to the ethnicity results from earlier this summer),shared migrations, and shared matches between the 2 samples. This is undoubtedly an improvement in information, though we still don't know which chromasome these shared segments are on.
This seems very useful in analysing which part of your tree a given match might be from!
Have others seen this? What do you think??
