XF 1.3 template modification question

this tutorial is awesome ive done my style with this guide but now im trying to make it better such as modifying moderator bar so if i go to modify a line and create mystyle_moderator_bar how would i go to overwrite the part of the code?


Replace the following:

<xen:hook name="moderator_bar" />


<xen:if is="{$visitor.user_id}">
<xen:include template="navigation_visitor_tab" />
<xen:hook name="moderator_bar" />
or should i just edit the xenforo moderator bar instead of creating my own?

or if i do create template modification will it export it?
Maybe i wasnt clear enough or i just dont understand the procedure but i have created a style i want to add visitor panel to the moderator bar but trying to make it so when i do it i dont do it directly to the template. then once done i want to export the style so i can have this once imported on the live style. How to do this or is it even possible?
