+This extension applies a set of eggbot-friendly
+default presets to the live path effect called
+"Hatch (rough)."
+
+It affects all objects in your document that
+already have the live hatch effect applied. 
+
+After using this tool to apply presets, use
+the "Edit paths by node" tool to change the 
+frequency, direction, and/or bending of the 
+hatching, by dragging the diamond control 
+points.
