Additional browser behavior to make the experience better

What feature would you like to see?

Hello thank you for the nice experience and the effort, while using Zen i came across certain things i wish to optimize:

1. i would like the pinned tabs to be always visible that way a user with many tabs shouldn't have to scroll all the way to the top, and i can imagine someone having many pinned tabs so you dont want that pinned tab section to take all the space for normal tabs so you may consider having a max height or something like that.

2. i noticed something which is when you open a new tab you need to scroll to the bottom in order to see that newly opened tab, if you could scroll automatically to the new opened tab that will be a great optimization

3. It would be great if you cant make the sound button more visible in tabs
