Ok, as far as i understood, the layouts are loaded accordingly to the app/etc/modules/Mage_All.xml file… If there is layout from the loaded module with <reference name="left"> it will replace the left block set in page.xml (whis is the default layout)… or? What if i write my own module with my own layout, will my layout replace the default blocks if i use <reference name="name_of_the_block">?
I also see that <reference name="content"> is what you add from your CMS Manage Pages admin menu, is there a way to override that? To keep it as default backup content and try to override it with my own content from the module i am creating?
Thank you in advance!
