Flatten legend, reduce depth of base block

[IanWorthington]

I have the attached image produced by plot_gg.

Is there anyway to flatten the legend? It, and its shadow, rather dominate.

Also, the base block is rather thick. Is there a way to slim this down?

I think you should be able to change the base block thickness by changing the value of soliddepth in plot_gg()

For the base problem try solid = FALSE inside plot_gg()
