The calendar, especially in month view, displays an awful lot of information. Therefore it is crucial that the information can be read clearly.

Currently, I can only tune the colours for the events. Depending on the colour, the event text is shown in black or white. This decision is not always optimal, personally I would like some blacks to be white and vice versa. This may, however, be related to the choice of the font used to display the event texts. I seem to have no control over that either.

So to be able to improve the readability, I would like to propose a way to select the fonts used, and a checkbox to toggle black/white rendering.
