User:Vlsergey from ruwiki presented yesterday at the Wikidata Meetup a new wonderful infobox editor for Wikipedia infoboxes: https://www.wikidata.org/wiki/Wikidata:Project_chat#Edit_directly_from_infoc...
And also an improved authority template which you can see in action at Obama https://ru.wikipedia.org/wiki/%D0%9E%D0%B1%D0%B0%D0%BC%D0%B0,_%D0%91%D0%B0%D...
Plus some interfaces for editing person info, taxons, and work/edition source info: https://www.wikidata.org/wiki/Wikidata:Project_chat/Archive/2014/07#WEF_gadg...
I think these are great improvements for editing wikidata from wikipedia and I hope you can spread the word in your local wikis about these wonderful tools.
Thanks! Micru
