src/components/sidebar/index.js:ListItem does not use target="_blank" but probably should #59
Description
The icon for additional links in the sidebar indicates that the link would open in a new tab. But the definition of ListItem does not indicate this. Perhaps it should be an option or it should default to opening with target="_blank". The other option is to use a GatsbyLink instead of ListItem in case the link is to another part of the site or to an external destination.
