Tag Count of all children

Hello,

Here is a sample of my website hierarchy :

Taxonomy 1
Book 1, Book 2
–Taxonomy 1.1
Book 3, Book 4, Book 5
–Taxonomy 1.2
—-Taxonomy 1.2.1
Book 6, Book 7, Book 8

2 needs :
1- Count all books from a custom taxonomy including children taxonomies
I tried : [mctagmap taxonomy=’taxonomy 1′ tag_count=”yes”]
Result is : 2, i would like to be 8

2-i would like to display custom taxonomy list of a given taxonomy parent.
I tried : [mctagmap taxonomy=’books’ child_of=”105, est-sint”], 105 being the ID of the taxonomy 1

Any hints ?

Cheers

Chris
