Thanks for my favorite applications.
Since I have enough RAM I usually dont close firefox and other apps when I give myself a break from work and put in some game time. So I would open process explorer and set FF priority to idle along with a couple of other processes.
It would be such a nice addition to process tamer to do this automatically. It could be implemented many ways, and I can easily see how tough would be the best solution to work out, but even a simple extension of the rows at the configuration tab would make the difference.
