Major UI changes

Code Review Tasks:

Author tasks (delete tasks that don't apply to your PR, this list should be finished before code review):

• If I made any UI changes, I've let QA know.
• I have ensured that the Heroku Review App has successfully deployed and is ready for PO UAT.

Reviewer tasks (these should be checked or somehow noted before passing on to PO):

• I read through the JIRA ticket's AC before doing the rest of the review
• I ran the code (in the review environment or locally). I agree the running code fulfills the Acceptance Criteria as stated on the JIRA ticket
• I read the code; it looks good
• I have found the tests to be sufficient for both positive and negative test cases

Is this needed? If this is hiding the element path in the status bar, the recommended way, and the way we do it in the component is to set elementpath=false in the config hash.

Oh yes it's responsible for hiding the element path, thanks for the pointer.

@andela-ysanni @slimeate What is the status of this?

[oluwayetty]

@egh it was pulled of of the sprint because of a PR from loofah that we want to make use of to round up the ticket.
