Installed; a very useful app; thanks!

Some suggestions for built-ins:
(sorry if these have already been suggested and I do recognise that these could be just as easily typed in...):

Set brightness like how the Display applet does it:
gconftool -s /system/osso/dsm/display/display_brightness -t int %d

Set the network mode:

And toggle the phone's radio:
dbus-send --print-reply --system --dest=com.nokia.phone.SSC /com/nokia/phone/SSC com.nokia.phone.SSC.set_radio boolean:false ["true" to enable]
