I like the new editor's pop-up preview mode - makes for editing tables, when you want some Accumulated data and have to preview the table to get some information from the previous row to add to the current row. No more scrolling the entire page up to get the information then scrolling back down to the Edit screen  the preview and then copy the current row information so you can paste it into the next row's information then (repeat for each row want accumulated data added)

Now you just place the editor where you want to add the info - click preview - copy the previous rows info, click cancel and you are right there where you want to add the info.

The single scroll bar (up / down) is great as well.
