Sometimes you don’t comprehend some of iOS’ animations/effects until they are gone. One such animations is the one that happens when you launch applications on your iPhone, iPod Touch or iPad. If you look closely, when you launch an application from your homescreen the icon temporarily gets a shadow and becomes darker. If you place your finger on an icon and just leave it there for a few seconds before wiggle mode initiates you can get a better idea at what I am talking about.
A tweak was released today called No More Shadows that takes away this shadow effect when launching applications and it really makes using your iOS device strange. Subconsciously this effect gives you certainty of the application you are launching, without it, when launching applications you question whether or not you launched the application you think you tapped on.
This isn’t to say that No More Shadows is completely useless, I am sure some people will like the experience, but it is worth noting though that for the most part I would avoid the tweak. The stock effect was implemented by Apple for a reason. Heck the Fruit Company even kept it in iOS 7.
