+# Admin Panel UX Refactoring (2025-12-11)
+
+**Objectives:**
+- Standardize UX across Admin modules (Loading Skeletons, Alert Dialogs).
+- Fix specific display bugs in Reference Data.
+- Improve Admin Dashboard.
+
+**Achievements:**
+1.  **Dashboard Upgrade:**
+    - Replaced `/admin` redirect with a proper Dashboard page showing stats and quick links.
+    - Added `Skeleton` loading for stats.
+
+2.  **Consistency Improvements:**
+    - **Modules:** Organizations, Users, Projects, Contracts.
+    - **Changes:**
+        - Replaced "Loading..." text with `Skeleton` rows.
+        - Replaced `window.confirm()` with `AlertDialog` (Shadcn UI).
+        - Fixed `any` type violations in Users, Projects, Contracts.
+
+3.  **Reference Data Overhaul:**
+    - Refactored `GenericCrudTable` to include Skeleton loading and AlertDialogs natively.
+    - Applied to all reference pages: Correspondence Types, Disciplines, Drawing Categories, RFA Types, Tags.
+    - **Fixed Bug:** Missing "Drawing Categories" link in Reference Dashboard.
+    - **Fixed Bug:** "Drawing Categories" page displaying incorrect columns (fixed DTO matching).
