Question about portfolio slug

This is a great plugin, thank you for your contribution! I have a question about the ‘Portfolio slug’ in the ‘General Settings’ – If this is set to ‘portfolios’, does this mean that all portfolios will be accessible publicly via that link (i.e. ‘www.website/portfolios’ )? Also, is there an option to hide entry-meta for each portfolio item? I know I can hide this easily via CSS but was wondering if this is a setting somewhere that I missed, or if this setting is available in the Pro version.

Also, is there an option to display portfolio items with a full width or sidebar layout?
