How can I add field into notebook/page (Tab) near name?
I want to display number of record in page. For example I have notebook/page with name ="Books"
and inside this page I have field One2many with books. I want to display count of books in this field in a front of string Books, so it would be look like:
(12) Books
How can I insert field directly to
<page string="Books">
<field name="book_list" />
</page>
