     - **Semantic Nudging:** Automatically prefixes tool and parameter descriptions with priority tags (e.g., [HIGH PRIORITY], [PREFERRED]) to bias model selection.
     - **Dynamic Tooling Strategy:** Automatically appends a Markdown "Tooling Strategy" section to system instructions based on the active preset and global bias profile.
     - **Global Bias Profiles:** Application of category-level multipliers (e.g., Execution-Focused, Discovery-Heavy) to influence agent behavior across broad toolsets.
-    - **Priority Badges:** High-density, color-coded visual indicators in tool lists showing the assigned priority level of each capability.
+    - **Priority Badges & Refined Layout:** High-density, color-coded visual indicators in tool lists showing the assigned priority level of each capability. Displays tool names before radio buttons with consistent spacing for improved readability.
+    - **Category-Based Filtering:** Integrated category filtering in both the Active Tools panel and the Tool Preset Manager, allowing users to quickly manage large toolsets.
     - **Fine-Grained Weight Control:** Integrated sliders in the Preset Manager for adjusting individual tool weights (1-5) and parameter-level biases.
