Simply put the "textarea" folder into your site/fields folder. The default textarea field will be overwritten and you don't need to edit your blueprints.
You can change the headline buttons to any headline from 1-6 in the site/config.php. The function, the shortcut (meta+1, meta+2, ...) as well as the icon number will adjust accordingly.
Example:
c::set('textarea.h1', 'h2');
c::set('textarea.h2', 'h3');
c::set('textarea.h3', 'h4');
You don't need all the buttons? No problem, just use buttons:
test:
type: textarea
buttons:
- h1
- h2
- bold
- olist
- link
