Stock Picking by Mail

This module adds a simple emailing option to warehouse transfers. On the transfer form (the stock.picking screen), a new "Send by Email" button appears next to the status field. Clicking it opens Odoo's standard email composer window, where the user can pick recipients, write a message and send it.

• The button is hidden for internal transfers, so it only shows for incoming, outgoing and other non-internal operation types.
• It is available to regular internal users.
• If the company has configured a stock confirmation email template, that template is pre-loaded in the composer; otherwise the composer opens empty.
• The email is linked to the transfer record, so the message is stored in the transfer's chatter/history.

No new fields, menus, reports or automated rules are added. The module only extends the existing transfer form and the stock.picking model with the send action, relying on Odoo's standard mail composer and templates.
