Comment 16 for bug 376579

Not sure that can help you, but if you use crm_configuration, seems to work on half (a lot of views are added).

i join a module use in my company to add on all views in base_configuration (it's a fork of one module i had in training in openerp for crm) and some adds to have contact even in sale and purchase.

Need to be test in general case (not only in my company) and surely split to have one module for sale and one module for purchase.

Just some remarks :
in crm_configuration, use of replace and string for label, so i need to replace partner_address_id (and not just change in .py)
in crm_configuration phonecall view, use of partner_address_id without call of onchange (it's a bug, but no time to create all)

Have a nice day.
