Hello, @designerobot
Thank you for your suggestion.
1) I have passed your request to our developers. But I have to say that they are working on header builder for the XStore theme and won’t be able to start improvements of the WordPress before finish the builder.
2), 3) Why don’t you add the portfolio category to menu http://prntscr.com/p6u60h ? Why do you need the separate pages?
Regards
