Hi there, We are excited to introduce a new feature to help you better organize and manage your paper library. Starting today, you can create and add custom tags to your uploaded PDFs. 

When uploading PDFs, simply click the new "Add tags" button to create a tag or add an existing one to your new papers. 

Then when starting an "Extract data from PDFs" workflow, you can filter your papers by tag by clicking the "Filter" button and selecting the desired tags for your data extraction. If multiple tags are selected, papers that have any of the selected tags will be shown. 

Finally, you can also manage your tags within your Library. Simply select the papers you want to edit by clicking the check boxes on the left. Then click the "Tag" button on the toolbar to add or remove an existing tag, or create a new one for the selected papers. 

Hopefully tags will help you more easily organize papers by project, category, favorites, reviewed status, step, or more. We are excited to see what tags you create! Happy organizing!
