Activator: The Must Have Jailbreak Tweak
In this podcast, Musicruz gives us an in-depth discussion and demonstration of Activator, a jailbreak tweak which allows for gesture-based controls of almost anything.
If your iDevice is jailbroken, it's likely that you already have Activator installed, even if you don’t realize it. Many other jailbreak tweaks rely on Activator to work, so they install it automatically as a dependency. However, Activator does a lot more than just work with other tweaks, and you can use it to make your life a lot easier. Things you would normally have to do manually on your iDevice can be done with simple gestures using Activator.
Activator is available from Cydia on a jailbroken device.

#1 Additional explanation
In the part where I was trying to kill the apps in the app switcher, it fails to kill the Apps. I know I should have explained what happened as well, but due to the length of the podcast. I was kinda tired towards the end, so here is the explanation on that one.
It fails to kill the apps on app switcher because I was currently inside the setting, which is also consider an app, so basically with the KillBackground tweak, it will not terminate any apps on app switcher if you are inside of any apps.
I apologize for not explaining this in detail on the podcast.
Despite of everything, You guys still find this podcast informative. Thanks for the kind words from all of you. I truly appreciate that.
Sincerely,
Musicruz
