Brought to us by the famed Ryan Petrich Running Indicator is a jailbreak tweak that adds a neat glowing indicator around currently running apps on your springboard.
Running Indicator also has an option to add a close button on running apps directly on your springboard without having to do it the slow Apple way. This will come in handy for those who have that pet peeve always having to close out their apps manually.
You can download this tweak through cydia via the bigboss repo. No icons are added to your home screen with this tweak and you can set up your options throught your settings.app.
