Could You Add In Themes like on Google Chrome:
This Would make brave so much better in my opinion
Theme support should be coming with Brave v1.0, which we will see in several months!
More info about Brave v1.0 from CTO, Brian Bondy:
Since we’ll have full extension support, we’ll also be able to support themes. We’re planning to bundle both a dark and light theme. We’re also planning to expand on additional items that can be themed.
