Hello Elefteris and Fotis,
Minor feature request for you guys: In Joomla articles, when an article is scheduled to be published in the future, the publish state shows a different icon (little yellow exclamation point).  K2 items show either published or unpublished.  

It's a minor thing but very useful when managing a large list of scheduled blog postings (and to one-up Joomla, maybe add a "Scheduled" option to the filter drop down?

Thanks,

--Olivier
