Moving controls smoothly around the screen

[Paul Hibbert]

Peter,

You can do a move in time, I had a go at an accordion style menu system (like your example below), but couldn't make the group reveal and move the remaining buttons simultaneously, although it didn't look too bad.

Anyway, the test I did is here if it helps…
