When using custom instances of caches, it's possible to, for example, create a memcached instance and name it "mymemcached".

Later you can assign (map) that instance to be used by both application and session caches.

Then, in the "Caches used (hits/misses/sets)" footer information, there is no way to know which type of cache (Application, Session, Request) is each box. All you get is "mymemcached".

So this is about to add something, perhaps A, S, R is enough, to know quickly the "mode" each instance is running on each box.

Not critical, but useful... IMO, for your consideration, ciao
