+A typical extension is to provide a mechanism to filter reports on analytic dimensions
+or operational units. To implement this, you can override _get_additional_move_line_filter
+and _get_additional_filter to further filter move lines or queries based on a user
+selection. A typical use case could be to add an analytic account field on mis.report.instance,
+or even on mis.report.instance.period if you want different columns to show different
+analytic accounts.

   involve much less queries to the database.
 
-* A mechanism to have a global move line filter at the level of the report template,
-  report instance, or even column. Such a domain filter would be ANDed with the
-  other filters and would allow to easily create reports filtered on analytic axis
-  or business unit. To be complete such a mechanism should allow implementing similar
-  filters on non accounting queries.

 * More tests should be added. The first part is creating test data, then it will be
   easier. At the minimum, We need the following test data:
