S2D will add a link to the data source of all items in Multilist, Treelist and drop link fields.
Sitecore straight to datasource adds new links against TreeList, MultiList and DropLinks allowing you to navigate to the datasource of any option item without having to go to raw values, copy, search etc...!
Click an option to display the link to the datasource.
Sitecore Straight to Datasource is still in beta so please send me any feedback.
