   <CHANGES>
+### 2026.06.21.r002
+- Reuse the expandable folder tree for local repository folders, Rsync targets, restore targets, and directory settings.
+- Preload complete snapshot file listings once and browse them locally in an expandable restore tree.
+- Remove the previous snapshot browser truncation and extend the snapshot listing timeout for large backups.
+
 ### 2026.06.21.r001
 - Add a separate emergency repository unlock action that invokes Restic unlock with --remove-all after a strong confirmation.
 - Keep the normal unlock action safe by removing only stale locks that Restic considers safe to clear.
