Sankey modify nodes/labels properties

Hi,

I noticed that the labels of the rightmost nodes column are automatically placed on the left. Is there a way to modify this and get the labels to be on the right? This, so it doesn’t cover the links.

Also, is there a way to modify the spacing between nodes? E.g. in the picture I would like to set the spacing from 30 to 50, and all the nodes would get vertically more separated.

Note: Using python 3.7 on Jup. Notebook.
