I would have a question: how can be solved, that let the calendar not display it based on the time of the making articles (created), but according to the end of the publication (publish_down)?
Currently the articles are displayed based on created_date only if publish_upnow.
Do you want to display articles by publish_up date?? I think is good, maybe in next version I can check if created_date!=publish_up and if so....display based on publish_up date. Thanks for the suggestion.
