PURPOSE
This commit aims to apply some cosmetic changes on the mass mailing
tree view to improve its usability.
SPECS
- New precedence order for the mass mailing views: With the kanban view,
mailings tend to pile up. When there are a lot of mailings, it can become
tricky to find a specific mailing given that the names of the mailing are
often generic and redondant (e.g. "Don't Miss Out", "Special Offer", ...)
For this reason, we will encourage people to use the list view by giving
the list view a higher precedence over the kanban view.
- Add progress bars for the delivered rate and the open rate (in the tree view).
- New column order for the tree view.
- Remove the unused and invisible field 'mailing_type' from the tree view.
- Set the fields 'mailing_model_id' and 'campaign_id' as optional.
- Minor decorator update.
