I'll try to alter to show the board and the pieces in side-by-side columns.
You mean the same table that you can otherwise open below it? You can already do that by including a HTML table element with id="pieceTable" (or xxxTable when you defined satellite=xxx). TheDiagram script will fill that with the table it creates. You would have to provide your own surrounding table, however, to force them side by side. (Or whatever HTML method you would normally use for that.)
The way it works now is that it looks for the pieceList id on the page, and only if it doesn't find one it creates an (initially hidden) HTML element with this id below the board to make sure there is one. And then it creates the piece table there.
