Easing .curves
Is there any custom "*.curves" that are close to this? http://www.inkfood.com/wordprez/wp-content/uploads/easingFunctions.png With bounce, elastic, ect?
Unity allows to save them to your project, I don't know why i couldn't google any. I'm currently using Unity 4.6 (don't know maybe it changed in Unity 5) I can't belive there is none that everybody uses.

Forgot to update the question when I got the answer from the different source
Thanks to the user @ntakushima on Twitter for linking this pre-generated AnimationCurve presets from Penner's easing functions. They are very useful for example for NGUI tweening or other standalone tweening libraries where you specify a tween in an Inspector. So here it is - Github: EasingCurvePresets
Check the plugin "iTween" on the asset store you can get all standard curves
