3-Column Search Builder: Combine keywords, date ranges, and review tags into a single search pass. Include or exclude tags as a search condition.
Custom Grid & Export Layouts: Show, hide, and drag columns into whatever order you want directly from the toolbar. What you see on your screen is exactly what gets exported to CSV, DAT, or Excel.
Mass Coding & Bulk Tagging: Tag hundreds of documents at once across checked rows or your entire active search set with one click, then get an immediate confirmation showing how many records were updated.
Dedicated Export Menu: We pulled the PDF and Native export tools out of the crowded Tools dropdown and gave them their own main toolbar menu so you can generate exports faster.
