Hello Felix,

Thank you for your purchase and apologies for replying a bit later, we don't work on weekends. 

1. There isn't a possibility to change this in Amelia with its current built-in features, unfortunately. You can maybe achieve what you need if you add custom CSS, like you did for the picture.

2. The customization options that are available for Amelia are on the Amelia -> Customize page. If that doesn't help you achieve what you want, this also can probably be achieved with applying custom CSS. 

3. It isn't possible for customers to sign up first and then choose a date/time in Amelia with its built-in features, unfortunately. 

We don't have CSS for that, we can help out with some CSS, but customizations are not covered by our support. 

 For point 1 I see one column for the booking form in Amelia, please look at the attachment. So, this probably depends on the screen you have. 

For point 2, you can apply this CSS for changing the back-ground color: 

div#am-confirm-booking {background-color: black !important;}

but then you need to make all of the text white to be seen, all of this is done by inspecting the page and finding the right CSS selectors 

 labels:

label.el-form-item__label {color: white !important;}
