Question

I haven’t found a way yet to customize what items are shown in the “list” view.
To be a little bit more specific : by default all the records in a database table are selected and displayed, I want to be able to tweak a little the database select in order to select only a subset of items from the table.

Answer 1

config:
  list:
    table_method: getForAdminList

Then, in a related model table class you can define your conditions to filter records:

  public function getForAdminList()
  {        
    $q = $this->createQuery('a')
      ->where('a.id > ?', 100);
    return $q;
  }

Notice that you have to return the query, not a collection of records.
