Adjusting margins in text boxes

+1 for this feature! Layout needs a text box margin.

Another workaround,which only works if you are not using partially transparent text boxes is to apply a stroke of 10 or 15 pt to the text box. Strokes this large are not given as an option in the dropdown, you have type them in.

By the way, if anyone from the Sketchup team is reading this, the tabs after bullets are too large.
