+Base Dynamic List
+=================
+
+Very often during an Odoo implementation, we need to add selection fields on a native objet, and we don't want to have a hard-coded selection list (fields.Selection), but a selection list that can be changed by users (Many2one field). For that, the developper needs to add a new object (with just a 'name' and 'sequence' field) with a form/tree view. The goal of this module is to speed-up this process by defining a dynamic list object that already has all the required views.
+
+This module provides several ready-to-go objects:
+
+* simple list : fields *name*, *sequence* and *active*
+* translatable list : fields *name* with translate=True, *sequence* and *active*
+* code list : fields *code* (unique), *name*, *sequence* and *active*
+* translatable code list : fields *code* (unique), *name* with translate=True, *sequence* and *active*
+
+These objects are readable by the employee group. The system group has full rights on it.
+
+To use it, you need to do 2 or 3 things :
+
+1) Add an entry in the domain field and the object you selected:
+
+domain = fields.Selection(selection_add=[('risk.type', "Risk Type")], ondelete={"risk.type": "cascade"})
+
+2) Add the many2one field on your object:
+
+risk_type_id = fields.Many2one(
+    'dynamic.list', string="Risk Type",
+    ondelete='restrict', domain=[('domain', '=', 'risk.type')])
+
+
+3) Optionally, you can add a dedicated action and a menu entry (otherwize, you can use the generic menu entry under *Settings > Technical > Dynamic Lists*:
+
+<record id="dynamic_list_risk_type_action" model="ir.actions.act_window">
+    <field name="name">Risk Type</field>
+    <field name="res_model">dynamic.list</field>
+    <field name="view_mode">tree,form</field>
+    <field name="domain">[('domain', '=', 'risk.type')]</field>
+    <field name="context">{'default_domain': 'risk.type'}</field>
+</record>
+
+<menuitem id="dynamic_list_risk_type_menu" action="dynamic_list_risk_type_action"
+parent="parent_menu_xmlid"/>
+
+Limitation: when you want to have different access rights on these lists depending on the source object, you should prefer to use dedicated objects.

+# Mail Usability
+
+Take back the control on your email
+
+## Feature
+
+- do not follow automatically a object when sending an email
+- better email preview, allow to select between the whole database object and not only the last 10
+- use a light template version for notification without link (link should be explicit)
+- add some additional style in the white list when santizing html field (see tools.py)
+- make the email template by default not 'auto_delete'
+
+## TIPS
+
+Never, never tick the 'auto_delete' on mail template because it fucking hard to debug
+and understand what have been sent (we should create a module with a crontask, that drop them latter)
+
+If the template of mail do not look like the same when saving it in odoo, maybe the sanitize style have drop some balise
+please run odoo with "LOG_STYLE_SANITIZE=True odoo" to understand what have been drop, magic warning logger will tell you everthing
