Paragraph component: the Text Shadow doesn’t appear to do anything & needs a shadow color picker and x, y, blur controls
Have checked and the text shadow appears to work here, some of them are very light (this is due to the setup in the current themes), you can override or create a new shadow style in the Theme Studio…
And here’s a fancy (and disgusting) shadow I created…
Oh Ok, those defaults definitely need updating - 
- I tried the Custom option for Paragraph - the inputs are not allowing easy updating and when clicking in the well to position the ‘puck’ - it randomly jumps around.
There is a problem with the SHADOW editor in the theme studio.
NONE of the shadow previews are visible when the UI is in dark mode. Switching the UI to light mode is the only way to see them. Using light mode within this editor might make sense only to make things visible.
