CIS ability "Show activities"

I’,m writing this since some of you may not know this (I stumbled on it just now myself).

If you click on “Sandboxed Apps” number, you’ll get to Active Processes List (sandboxed only), right click on any process there and you’ll see “Show activities” menu. It’ll show you what process was up to…but this menu isn’t always active for some reason.

I don’t know if this was in V7, or this is new to V8.
