Add more custom fields to client data in backoffice Suggestions

Hello,

There is any way to add custom fields to custom data in backoffice?

The point is to have an custom costumer data for example gender, vat number, problems (like heart problem, etc…) and so on. To have an history of the customer more complete. Or adapt using probably using ACF plugin?

Also it is possible to export the bookings of the week or month for stats? Or any kind of stats?

Also check the visual issues on default theme Twenty Fifteen for example the font-size in the #sln-notifications, the size/space of datepicker in .timepicker .datetimepicker-hours

Tanks,
