At the moment it does not matter which category you are browsing, it always says 'Add Rescource' at the top right corner. Why not let the user know which specific resource he can add depending on in which category he actually is. So let's say I am in category 'Importers', I would expect to see at the top right the button 'Add Importer' instead of 'Add Rescource'. Does that make sense? This is a small change but it tells the people of what specific item they can add.
