Would it be possible to combine the Home Tab with the Library Tab so that everything is visible on one page?

Either remove the My Activity section or design it to bring more value. This is only providing the user the status of a Feedback request and does not bring any value. Potential Updates:

1) Show the exact feedback message left by the user.

2) Allow admin to enter comment in Habitat that would display to the user in the My Activity Section

2a) Received request

2b) Outcome of Request

Ability for the end user to see the change on the document or at minimum a link to the document so they can view what information has changed.
