I really like the aesthetics of iOS 7. But, there are some inconsistencies in underlying UI concepts (mainly multitasking-related) that make you appreciate the restrained simplicity of prior versions as well. Exhibit A Multitasking UI. Apps that are to the left in the multitasking view (the card view) are to the right when doing the 4-finger side gesture. Or the other way. Thing is, the spatial relations do not match in those two UI concepts. Exhibit B Swipe-up gesture. You would expect the card view to just slide upwards. But iOS 7 does this weird angled movement to the last opened app. This is behavioural consistency as it does the same thing as Home doubletap, but it's spatially weird and physically wrong. In prior verions, you directly manipulated the tray. Exhibit C Orientation issues. With live app previews in multitasking card view, you get wrongly oriented app previews if you rotate your device since you have last closed them. This is a repercussion of the whole live preview concept and AFAIK cannot be solved elegantly (you'd require apps to simulate a change of oerientation internally or something). There have to be many more examples of this. UI design is tough. These seem like nitpicks, but issues like this DO add an additional cognitive load, something that was so low compared to other systems back in 2007. What do you guys think?
