How do I alter/update the HTML

Hi there,
i am trying to adopt the “augmented reality” sample to my needs, and in a way i get done what I need to get done. I am working in Blender and For now I switch off the visibility and the “render object” properties for the little farmer and replace him with the model I want to use and when I do a local “sneak peak” it seems to work ok. But if I upload the project and test the project, my object is gone and the farmer is back … why?

How do I update the HTML file in a project? The update application seems not realy to do anything.

Then how can I rename projects in verge? It seems as if I only can rename files when I open the explorer and rename files here.
Regards
Heiner
