Very well done! 😄

Looking great @cezaraugusto. This mostly reduces the somewhat jarring effect when traveling across the tabs which is already a nice improvement.

I did find one issue when it is fading between tabs. The current active tabs appears in the middle. I suspect this is because it is showing through.

Is there any way we could set it up so this doesn't happen? (see screen shots)

It also seems to pop the new tab preview while fading out the previous. Perhaps adding a fade in for the new tab would solve it?

Hey @bradleyrichter, good catch.

About the current active tab appearing in the middle, there's an issue I'm currently working on, here #142.

About the new tab preview popping, the fade only happens for previews. Maybe tweaking with animation duration and timing-function could fix it. It's currently set as ease-in, maybe ease-out would be better. Will play with to see which fits best 😋 and ask you for feedback, thanks.
