The Stock rom that comes preloaded on your phone is often the most stable build that you can run, however it also often lacks the tweaks and mods that make it super fast and efficient, and even more importantly it lacks the custom features that you need. Most stock roms don't make it easy for you to reboot your device. You have to physically turn the phone off, wait a few seconds, and then turn the phone back on. To get to recovery or bootloader you would need to turn the phone on while pressing buttons in a unique order. Most custom roms come with a full reboot menu. Thanks to developer "kennethso168" you no longer need to ditch your stock rom to get a full power menu. His module adds this feature through the Xposed Framework. It includes a full reboot menu that will allow you to reboot your device as well as boot to bootloader and recovyer. It also includes disable mobile data, quick dial, screenshot, airplane mode toggle, and ringer toggle. This will not work with Touchwiz devices and you will need to be rooted and have Xposed Framework installed. Grab the module from the source link below.
