It would be useful if the colours set upp under categories could automatically be transferred to the appearance settings for a given event.
So, for example, if I define a category of "Urgent" specifying While text on a Red background and then later create an event and assign it the "Urgent" category, it would be nice to have the appearance settings automatically change to White text on a Red background (or at least have a single tick-box to do this).
Currently, I have to set the appearance manually for each event.
