As an elementary developer, the feedback is appreciated :)

Can you suggest an alternative to the bounce?

Hey, thanks for being cool about it. I'm not sure a good alternative would be, but I do have this advice. Google often takes ideas from competitors and remixes them to the point of making them original (a good example is the gesture password on the Android lockscreen). You can remix ideas from competitors. So in this case, instead of a bounce, a spin could work.

I'm nowhere near an expert but I thought this could help.

Thanks for the advice, and I definitely see where you're coming from. I tend to be an advocate of the "take good ideas but make them seem different" approach, but I think a core philosophy in elementary (perhaps to its detriment at times) is: "don't change for change's sake". I wrote more about that philosophy, and the general perception of elementary copying OS X in my comment here: https://news.ycombinator.com/item?id=6193676

There is a key difference between making a feature seem different and actually re-engineering it. I assume you meant the latter, so I just thought I'd offer some advice on word choice.
