Make sure you read the wikis on these things before you install.
Kernel Power has a lot of features that are CLI.

If using Kernel Power for SmartReflex you could install QCPUFreq.
This this will allow you to enable SR via a GUI. Also overclocking will be disabled unless you enable it in the settings.

For me the main applications to install are.

• CSSU

• KP

• Swapo

• QCPUFreq

• cpumem-app

• CSSU Features Config

• Orientation Lock Applet

• Rootsh

• Simple Brightness Applet

• QBW

• Wifi Switcher

• *# Enabler

There are loads of threads for most have apps, have a search.
But remember the more stuff/widgets you put on the device, the more chance your device will become slow.
