Is TabPageViewController able to customize the tab looks like round corner rectangle?

Hi,

I have designed an Android note taking app, which looks like a real world notebook with bookmark.

Real world notebook with bookmark

Android app

According to feedback, the "tab" design is the most loved feature, because users can switch between different labels easily. I would like to apply this design in iOS app too.

In Android, I implement such look and feel using TabLayout, with customized background drawable.

I look at your library. It is very impressive. However, I was wondering, by using your library, can I

1. Customize tab so that it is a round corner rectangle?
2. Have the following scroll behavior - https://youtu.be/4YH4-r4DTwU

Thank you.
