Functionality Recommendations: It is recommended that the right side of the batch add tags page to increase the corresponding properties under the label to add. Scenario, a pdf reading at the same time annotated multiple pdf, and then are added to the book annotated under the label, because it is the same book, so many properties are the same. And then go to the tag page to add batch is too much trouble, not as directly in the multi-card batch to add annotations can be set directly to the same properties
