If I have two different methods that I want to analyze but I do not want both of
them profiled at the same time, then I have to switch back and forth between
them.  This is not as easy to do as it could be.  The problem is that the list
of Selected Root Methods (in the Specify Root Methods dialog) is just that: a list.

What I need instead is something with a check-box next to each method.  Then I
could go find all the methods I'm interested in and have them listed.  By
default each would have the check-box selected, meaning that it is going to be
analyzed as a root method.  I could un-check the ones that I'm not interested in
at the moment and then start profiling.  Later, if I decide to modify my
profling settings, the check-boxes would make it really easy to modify which
methods get analyzed during the profiling session.
