Upgrade Storagedrag and drop
sometimes I need to record bibliographic data from a website that zotero doesn't recognize. Unfortunately in these cases you cannot mark, say, the title of a book and drag and drop it into the title field in zotero. You have to copy, go to the field in zotero and paste. It's nothing major of course, but as pretty much any program allows drag&drop it's not nice to have to do a few extra steps
There's also been talk of a feature that would let you select text on a web page, right-click, and select the field of the current Zotero item into which the text should go from a submenu on the content pane context menu.
