CAFu is a FuBar plugin with a couple of very simple purposes:
1. Give users the option to smash a button and see the in-game Calendar without having to view that huge-ass button on the minimap (it's called MINI for a reason; don't you think?)
2. Give users a simple and quick way to see what events will happen today, simply by hovering over the fubar-icon.
Of course, I'll be adding more options and stuff later, once I've thought of some. Currently I'm planning to add an actual icon (I know, I'm slow) and change the event-titles to actual smashable links.
EDIT: This addon used to be called FuBar - CalendarFu, however due to a project with that name already existing (and search not showing it when I first created this) I have been forced to change the name. It is now called FuBar - CAFu.
