Tree Header Buttons Always Visible

What does this module do?

This addon allows you to override the default functionality of the header buttons of the tree views, allowing the buttons to always be visible in the header.

Basic usage

Add {'always_visible': True} to button attrs.

                    <field name="field_name"/>
                    <field name="field_name"/>

Known issues

• Methods called from button should not be decorated with @api.model
• If the method contains a call to ensure_one it will only work if a single record was selected in the tree view. However, you can catch the exception
