 ## Features
 
 - **Syntax highlighting** for x86 (NASM) and ARM assembly
-- **Three display modes:**
+- **Four display modes:**
   - `raw` - Assembly with syntax highlighting only
   - `hex` - Hex bytes + assembly instruction
   - `full` - Address + hex bytes + assembly instruction
+  - `ida` - IDA-style section:address + assembly instruction
 - **Capitalization option** for hex bytes and addresses
 - **Dark/light mode** compatible
