Okay I am just getting some time checking out BSS 7. Man, this is a whole new learning curve. I have been using Blocs since version 2. Still using the newest one v6 Plus. There are known good designer templates for Blocs. I am sure there are 3rd party Bootstrap Studio where (.bsdesign), would anyone chime in here and share what they have found. Thank you
I am grateful for putting this together.
