FIN first, but then make it easier to navigate to the home tab (one click preferred)

We like the FIN first experience where the launcher opens directly to a FIN conversation, however, we would much prefer if when the back arrow is clicked that it took the user to the HOME tab instead of the MESSAGES tab. We have a lot of good stuff on the home tab, and some of our users don’t understand that they need to click the back arrow and then click again to get to the HOME tab. 
another idea would be that in the FIN conversation window, below where you enter your question, you could still see the launcher tabs for home and messages, etc.
