Here's how Apple can improve the iOS 7.1 keyboard

  In iOS 7.1 the company Apple Lossless Audio CODEC (ALAC), changed the functionality of the key SHIFT of the virtual keyboard, so now the button is marked in a different way when it is enabled for use. Many users are dissatisfied with this change made by Apple, and a graphic designer he thought to provide us with a method by which the system can be improved quickly. In the image below you will see the modification he proposes, it being borrowed from Androidbutton SHIFT being marked differently upon activation.

  Even if now it seems unlikely that Apple will change anything, the large number of users complaining about the problem could convince the American company to change the way the button works.
