Let me start with how I think the SystemProfiler is such a Great looking tools and so very well design ! haha !

Summary
Very nice SystemProfilerView, but it was implemented as a SystemProfilerEditor and it's the default one ... Where has 
gone the preference for the Default SystemProfilerEditor.

CPU Usage
Could the thing fully support event propagation between SystemProfilerEditors when I lock it ? It would also be nice to 
be able to switch to one of the 3D charts when I select a couple threads. It a multiple selection scenario the area 
chart is useless and 3D line chart is a lot more visual then 2D. Except for selecting the element the table is not that 
usefull, I would like to hide it and select elements through an editor from a different pane ... Maybe it would have 
been better to just leave the old ProcessActivity editor ! haha !

Timeline
Has any new features been added to it in the last 3 years, I could'nt find any ?

SystemProfilerBar or TimelineBar
I don't remember the exact name ... Nice look improvement !
