I've posted a similar request here: https://project-gc.com/qa/?qa=13324/feature-request-more-cache-types-in-overview-caches-per-dt
Unfortunately, ganja1447 replied it's not feasible at the moment. Which I think is a real bummer, since the D/T grid is (for me at least) the most interesting part of the profile stats. This is a must have feature in my opinion.
edit: Wait, what?! There have already been added some more cache types? Wasn't aware of that, have I missed an announcement?
