Cool new applets…

Now that gnome-power-manager can do trivial applets, I'm open to suggestions to what would be sane to expose to a power user as additional “manually add” features.
Ideas I'm playing with at the moment include:

• Hotspot applet : click the icon and the computer won't auto-suspend or blank the screen until it is clicked again. Useful for proprietary programs that don't support the Inhibit() interface like matlab or vmware.
• CPU frequency scaling applet : i.e. a re-implementation of the existing cpufreq-applet but using g-p-m to do the policy and HAL to do the heavy lifting. Should be tiny in comparison to the old applet (and not be setuid), and would work well with existing g-p-m policy.
• Logout, suspend, hibernate and shutdown icons (power-applet) : i.e. a set of icons that provide one click access to these functions (and that hide individual icons if you have no support or not enough permissions). i.e. a distro would add this applet, and it would show the right stuff on the right computers.

Feel free to suggest other “cool applets”, or just tell me I'm insane. Thanks.
