Make it easier to "go back" in routes page

[hathix]

When you see a page like this:

It's hard to go backward. How do I go back to information on the route-1? I guess there are the red X's, but it's hard to know exactly what they do. It's even harder to go back to the metrics page without knowing to click on the active metrics tab again, which isn't intuitive.

The old breadcrumbs UI solved this quite neatly. I wish we could have something like that again. Even something as simple as a back button somewhere.

Besides clicking the X next to Direction, you can still use the browser's back button. I don't think the UI itself necessarily needs something that does the same thing as the browser's back button.

The main problem with the breadcrumbs UI is that it took up a lot of screen space showing the same information that was also shown in the dropdowns.

Perhaps the Metrics tab could be deselected on the route screen. You can also go to the metrics page by clicking the X next to route, or using the browser's back button.

I'm open to ideas for clearing fields that could be more obvious than the red X.
