Even though I change the fields (custom or not) order in the Custom Fields screen in Mautic, that order doesn't reflect in the Contacts screen.
How can I customize the order and position of fields in the Contacts screen?
Since I didn't find a solution ready for this need I decided to customize the leads form myself. After taking a look at the code I noticed it's really easy to change and maintain.
The solution was to order/position the fields directly on the view: app/bundles/LeadBundle/Views/Lead/form.html.php.
