• The menu of the top banner doesn't seem very useful to me. Right now it always shows the same 4 things from the action menu of the top page, which is probably not what you intended. But even if it changes per page, I think it'd end up just repeating what's on the left.
• I liked our recent breadcrumb that sticks to the top of the page.

I agree with him because:

• Jenkins pages are highly hierarchical. Breadcrumbs may become longer especially when we use JUnit Test Result, Analysis Plugins and Nested View.
• The first item of the breadcumbs provides a link to root. I don't think a.brand should be always visible.
• I seldom click "USER_NAME | log out" links.
