In order to set the number of tiles pr page use the posts=’#’ attribute [post-tiles posts=’2′] This controls the number of tiles loaded on that specific page.
By default it should show 4 tiles unless you set the global setting which overrides the default.
Regarding the change with the responsive layout it seemed to make more sense to make it responsive to the container not to the overall page. This would make it generally more flexible in case it’s placed in a smaller space.
I can look into adding another break point for big screens but this adds a layer of complexity. With the current responsive layout it starts with 4 then breaks to 2 on medium, and 1 per row on small. How many would be in a big screen 8? Otherwise if you have 6 and you scale down to 4 per row you end up with two rouge tiles.
Thoughts?
