I couldn't get a page by Site Layout Customizer 1.7 to do paging. It only shows the defined amount of new posts, but that's it. It doesn't display a link for older posts, or show the page any differently even if a suitable URL is typed manually. For example adding /page/2/ to the URL doesn't change anything.
To make a sensible front page, the plugin should be able to handle the correct URLs so that WP-PageNavi could be used to add the user interface for paging.
As an aside, the current link on homepage to FAQ, http://1customize.com/?page_id=254, returns a 404 error.
I've added many suggestions today, and I know that if they and some of those raised in your blog can be addressed, this could become one of the must have WordPress plugins. I hope you continue its development without any doubts of the good work you're doing.
