Thanks for the write up!!!
We’re in the process of doing a similar project with a site with another level of navigation to deal.
We came up with what I thought was the best solution, slightly different than your final solution on greenbelt but mostly similar.
One thing I have noticed is I’ve had to change a few layout options I previously thought were good ideas….. until I saw them in practice.
We’ll be launching early May so hope to post something along the same lines then.
cheers again.
Justin.
