A nice idea, something I planned on doing anyway. I'll see what kind of designs I can come up with and then condense all the designs in one thread so that members can grab the associated "celebration days" in one area.
Off the top of my head the ones that come to mind:
5th November (bonfire night)
Thanksgiving (although us english don't celebrate this)
Problem though is that the height on what I can build upon is restricted. 30px as seen on xenforo is now at 25px. That said, I'm sure there will be a workaround for this I managed to get a workaround on my localhost. When time permits, I'll see what I can conjure up.
@hcmagix - I feel this thread would be better placed in resource discussions because once designs are crafted out we can further discuss on what can be tweaked in the design and code thus perfecting the design & code so that it sits on the navigation nicely. It's your thread and of course, your call
