In beta testing an iOS application I wrote, I received some feedback to let more elements 'bounce', even if there isn't more content to see, or load in.
While I don't think its necessarily a bad suggestion it got me thinking - what is the purpose of allowing this behavior on UI elements? Is this stated in the HIG somewhere that I missed?
If the list bounces you know that it is at the end instead of just frozen or something. It feels good to get feedback whenever you touch something even if nothing is happening.
