If you’ve ever noticed the name of an application on the left side of your iPhone or iPad’s Status Bar after being jolted from one app to another, then you’ve witnessed what Apple calls a Breadcrumb link. This handy link lets you get right back to the app you were just using when you’re finishing in the app you were just jolted to.
I really like the concept behind Breadcrumb links, but if there’s anything that really grinds my gears about them, it would be the fact that they can sometimes remain in the Status Bar even after you’ve forcefully closed the origin app. Tapping on the Breadcrumb link is often the only way to get rid of it, and then this would would re-launch that app whether it was needed or not.
