Edit default views (books, basic page, etc) I am using Views 3 with drupal 7. Views provide you some default views so you can edit them and customize them.

I want to do the same thing, for example, with book pages. I don't want to start from scratch with a new view. I just want to edit the default view of book pages.

Is there any way of editing it ? Or should I go directly to the code ? If so, which code is it ?
You can edit any existing view. Go to the views list and click on enable button that you would see on the view that you want to edit. Then you would get access to go inside the view and make your changes.

Hope that Helps.
