I'm trying to figure out how the "slide in slide out" effect is done.
Here is an example in an apollo app: http://www.finetune.com/desktop/ (pretty cool app by the way!) When you start finetune desktop up and click the arrows left an right you see how one things slides in and one slides out? That's what I want! How the heck do you do it? Is it a tween? It looks like there is a non-linear easing function on it but I'm a noob to effects. Thanks for your help in advance! :)
