I don't understand how creating a new activity represents an improvement to 
the user.  If I understand the proposal correctly the user will only use the 
power manager to change existing profiles and if they want to create an 
alternative profile they will have to us something that is not the power 

I understand the concept of activities for things like plasma-netbook with 
search and launch and newspaper actitivies.  It makes complete sense.  So I'm 
not unfamiliar with the idea.

I don't understand how it relates to power management.  Splitting how one does 
power management into two pieces is just going to confuse people.
