How about having the Jupiter applet ( http://www.jupiterapplet.org/
) on Linux Mint by default. The main reason I suggest this is because it is similar to the CPU scaling applet already on Mint, but unlike the CPU Scaling Monitor it has the ability to save performance mode upon restarts and between AC power and battery power. In addition, it is a very small package that is lightweight, and has additional functionality such as device control (turning on/off WiFi, webcam, bluetooth), changing screen resolution, screen orientation, displaying CPU temperature (hover mouse over icon) and even choosing between external and internal monitors which can be very useful even though I don't have an external monitor to test it out. Pretty much it is a great supplement in conjunction with the CPU scaling applet or even to replace it. But, preferably a modified version would be awesome since there are cons. It doesn't show the actual clock speed, which I enjoy, nor does it have the option to set CPU clock speed to a concrete given set speed (931mhz, 1.33 ghz, and so on) like the CPU scaling monitor applet does.
I am a total newbie and don't know much about the Linux development process or anything about open source software, but I think there is interest in this, including from myself.https://bugs.launchpad.net/linuxmint/+bug/618541http://ubuntuforums.org/showthread.php?t=1274455
