Minor issue; it is only a visual issue. Modify the [timezone widget link](https://github.com/thomersch/openstreetmap-calendar/blob/master/osmcal/templates/osmcal/partials/event_form_timezone.html) so that the mouse cursor on hover turns into a pointer. Currently acts as if it were regular text. (See [change cursor to finger pointer](https://stackoverflow.com/questions/8809909/change-cursor-to-finger-pointer))
