DZDropzone
From dataZoa Wiki
The dZDropzone tab shows all of the series in your account, grouped and ordered as they were first added to dataZoa.
Whenever you add data your account, the new series are shown here as dataBlocks. A dataBlock is a set of series that group together naturally. They are shown most-recent-first, with new series (or series that have just been edited or re-calculated) moving to the top of the page.
Series can form a dataBlock because they were:
* Dragged in from the Web as a group, using the dzDot * Manually uploaded as a group * Explicitly grouped by you
This means that dataBlock membership can change dynamically, but you can drag a dataBlock to a new or existing tab and fine-tune the dataBlock there.
