cfa_fit_plot, add covariances of items on plot? Problem is that is does not keep a vertical structure so does not look pretty when putting the default to TRUE. Perhaps there is a programmatic way in lavaanPlot to specify a vertical structure at all times.

nice_fit: automatically pick robust fit indices, if available(?)

nice_tidySEM:

Allow specifying BOTH standardized and unstandardized coefficients on the same figure, e.g., c("b", "B").

improve algorithm when odd number of variables for layout matrix by adding two empty rows around the odd levels, and one empty row in the middle of the even levels?
