I'm in the middle of creating a plugin that needs a template to display information stored in some records when the user clicks this in the CMS sidebar.
I've managed to get the template to appear (Yay!) And I've been looking at other plugins with regards to styling / structure of these pages.
A lot of them are extending and using classes that appear within Craft.
Is there a reference to this anywhere? Such as a class / styleguide or any where I can find out a bit easier what blocks etc are used?
