How can I see which collections an item is part of? I moved back to Zotero from Mendeley a few months ago, and this is one of the major frustration points. In (the old version of) Mendeley, I can click an item, and all collections that contain it would be highlighted. In Zotero I can't find any way to determine which collections it's in. This can actually get confusing as trying to drag an item to a collection that it's already in does fail, and it's not always clear if this is just a GUI glitch.
