Romain and I were talking about this over the weekend. It looks as if the implementation turned out quite nicely.
Wobbling Options UI Almost every application provides a nice options dialog in which you can, well, change some values to adapt the appearance of the behavior of the application. These options dialog alway contain a Save or Ok button and a Cancel one. Unfortunately you rarely can see what your changes actually did and you might even wonder whether something actually happened. I find it very frustrating. What if our applications showed a nice visual effect to prove your click on Apply really did something?
