hawk lets you use and create patterns over and over as templates.
templates will show up in the “make” menu.
the standard templates live at /~/system/templates
you can create your own templates in /~/config/templates
when you “make from a template” you can creating a hawk-500 page with a %twin load pointing to the master template.
when the template updates, all instances of it will be updated (sent an empty card) as well.
