Finding features in iPhoto for iOS
In delivering software user interfaces, there has always been differing lines of thought. One major thinking is to provide absolutely everything in full view, regardless of usefulness or practicality. This allows users to be aware of everything that the software is capable of doing, providing them with complete visible access to its features. Another is to only show the features that are most likely to be used and hiding the rest for users to discover as they become more familiar with the software.
The user interface in iPhoto for iOS seems lie somewhere between the two. Visually it’s a bit of a clutter but it also still has hidden features not accessible through the on-screen buttons and icons. Unfortunately those hidden features are very unlikely to be discovered unless people had seen the on stage demo when the app was introduced or that they read reviews and guides for the app on the Internet.
