for Hymalia I submitted a patch that showed different background colors in appointments - depending on the tag that has been set.

I cannot find that functionality in Hyperion so I guess that patch has not been integrated.

We really need those colors so I thought of abusing the 'Display As' properties. When adding/editing an appointment one can set this appointment to be displayed as reserved, temporary, absent on business, or free. This way you can mark the date with four different colors.


Is it possible the extend this list with additional colors?
Does using these properties have a functional impact on the dates?
