Vertically aligning all items in a Palette

is it possible to vertical align the palette?
in the GSA example, the black bordered box is a flexbox div that takes full height with flex-grow, then I would like to align the nodes within the vertical center of the palette.

The original question dealt with how to rearrange the positions of items relative to each other. Your question involves how to position all of the items within the viewport. That’s a different question, so I have moved this to be its own topic.

I think you want to set the Palette’s Diagram.contentAlignment to go.Spot.Center.
