Scrolll bar customization

I just migrated from microsoft edge to brave due to edge eating too much ram causing lags.
There’s a feature I really liked in edge that is missing in brave though. The scrollbar design looks way better in edge while in brave it looks old and too wide in my opinion, it would be really cool if users could customize the scroll bar width. The customization of the width could add a bit more screen width to a webpage which is nice.

Thanks for your consideration, I would really love to see this feature implemented.
