It is great to have application filter feature in 2.2, so that we are starting using data overview.

There is a very common case, when we want to check top 10 busy servers, if there is a sorting button that we can judge from a few different metrics, like mem/io/cpu, that will be great!

Just like, we can sort when we are checking configurations for items. Very appreciate that you can consider that as a new feature of data overview, and it become more useful for large site user!
