+## New in v1.14.9: Filters, columns, and exports
+
+### Filter presets (Save/Load/Delete)
+- Open the Search/Filter panel (Ctrl+F), set filters, then click Save to store a named preset.
+- A themed modal dialog asks for a name and shows if you’ll overwrite an existing preset.
+- Load via the presets dropdown → Load. Delete via Delete.
+- Presets persist across restarts.
+
+### Persistent column widths and sort
+- Resize columns; widths are saved automatically and restored next run.
+- Click a header to sort; the last sorted column and direction are remembered and re-applied on refresh/startup.
+
+### Export current (filtered) data
+- In Export (Ctrl+E), choose scope: All data or Current filtered view.
+- Works with CSV, JSON, XML, and PDF exporters.

+#### Presets and Persistence (v1.14.9)
+- Save/Load/Delete filter presets directly from the Search/Filter panel. Presets are named and persist across restarts. Save dialog is themed and shows overwrite/new hints.
+- Column widths and last sorted column/direction are remembered. Resizing headers or sorting stores preferences; they’re re-applied on refresh/startup.
+- Export can target the current filtered view: choose in the Export window to export only matching rows (CSV/JSON/XML/PDF).
