I'm trying to learn to use this tool, but a fairly simple need - that of reordering bookmarks in a list - is not available to me. The video tutorial indicates that bookmarks can be reordered in list view by simply dragging and dropping the bookmark. However, on my Mac running OS X 10.6.2 and using Firefox 3.5.6 with Diigo 4, there is no drag and drop.
Am I missing something here?
