If you haven't already, create a new outline and call it menubar.
At the top headline, write something like Scripts. This will be the title of a new menu bar sitting to the right of Docs in Fargo.
Create a child node and call it Star.
Then create a child node for that node, and enter the following:
Refresh your browser to load the new menu.
In a different outline, click on a headline then choose Star from the Scripts menu.
This will work for any icon, you just need to sub out star-empty with the name for any other icon from the icon cheatsheet.
