I use Phoneweaver for the same thing. Maybe not as powerful/flexible but I find it easier and does everything I want.
I've a quieter work profile. A louder one for when I'm out. One that goes silent when theres a meeting with a certain keyword in my calendar and one that switches on PowerAmp and starts playing when I plug in my headphones. I also have a calls and texts only one when I need my battery to last.
These tools, there are a few around, are what makes Android such a joy to use....that and flashing roms anyway!
