Sidebar Folders hack for Asana
This extension is a hack for Asana to get sidebar folders.
In order to create a folder, create a project with a name that ends with ":", e.g. "Private Projects:", and favorite it. Anything below that favorited project in the sidebar will be considered as belonging to that folder.
IMPORTANT: This is not an official Asana extension, and thus may not be supported by future versions of Asana.
