The style of tabs could be improved in Breeze, to be flatter and look more modern, as well as responding to the users current colorscheme.
Test Plan:
Before:
{F8191472, size=full}
After:
{F8191470, size=full}
PS: I made the mockup with a stylesheet, so some of the other graphical elements may have come out unstyled, like the progressbar at the bottom.
