@Richard-K any update? I think I will have to switch to another theme considering that we are talking about a woocommerce integration since 2016? Honestly I was quite enthusiastic about laytheme when Armin said there is a chance that WooCommerce integration will come this year. Now I started to feel there is basically no deadline set for this task, and I really need a webshop especially in this situation, and cannot afford waiting for it for another year, even 6 months would be very painful. I would be quite surprised if I am the only one. Why not hire someone who could help you developing the integration, I am sure you will have plenty of income to cover that after the integration is done.
P.S.:
Happy holidays!
