If you anticipate exporting items in specific different categories often (e.g., newspapers and correspondence), you may wish to have two separate instances of the plugin so you don't have to switch back and forth between your Newspaper template and your Correspondence template in the Plugin settings. To add another instance, click on the plus sign next to the first plugin instance to add another instance and customize it as you wish (without deleting the first instance). Be sure you name it something different!
