Like you said… first change
plugins/jigoshop/admin/jigoshop-admin.php – around line 40 – the add_menu_page for the main menu – last parameter controls menu position (default is 57 i believe) – for mine i changed to 100
the “products” and “orders” menu positions are set in …
plugins/jigoshop/jigoshop_taxonomy.php – search for menu_position and change to 101 and 102
this will structure the menu to be more logical and group all of the Jigoshop menus together at the bottom
Sorry, not sure if someone can edit the title and my post, but it is Jigoshop, not Jigashop … always type that wrong, hehe. May help later for someone searching.
