One of the more useful features Apple integrated into iOS is the Breadcrumb link function, which is accessible from the Status Bar. With it, you can go back to previously-used apps more quickly after you’re redirected to another on your device.
Despite how handy it is, people aren't so fond of their Status Bar getting cluttered up with extra text. Fortunately, iOS developer Sticktron found an aesthetically-pleasing way to improve your Breadcrumb link trail in his new free jailbreak tweak dubbed Croutons (iOS 9/10).
