 1. Added a 100ms initial delay to allow render completion
 2. Implemented recursive element search that:
    - Searches through nested children up to 5 levels deep
-   - Checks shadow roots of elements
-   - Handles complex DOM structures
+   - Checks both light DOM and shadow DOM for all elements
+   - Handles complex DOM structures generically
+   - Works with any wrapper elements, not specific to dees-demowrapper
 3. Added retry mechanism with up to 5 attempts (200ms between retries)
 4. Improved error messages to show retry count
+5. Comprehensive error handling:
+   - Errors in element search don't break the update cycle
+   - Individual property errors don't prevent other properties from rendering
+   - scheduleUpdate always completes even if createProperties fails
+   - Clears warnings and property content appropriately on errors

-2. Properties panel waits, then searches recursively for the element instance
-3. If not found, retries with delays to handle async rendering

 - Browser support information
 - Complete examples for all major features
+
+# Enhanced DemoWrapper (COMPLETED)
+
+## Modified runAfterRender callback:
+- Now receives the wrapper element itself instead of just children
+- Provides full DOM API access (querySelector, querySelectorAll, etc.)
+- querySelector works on slotted content (light DOM children)
+- Access children via wrapper.children property
+- Updated documentation with correct import path (lowercase 'demotools')
+- Examples show how to use querySelector for powerful element selection
+- Added clarifying comment about querySelector working on slotted content
+
+## Fixed Properties Panel Compatibility:
+- Made element search generic - works with any container elements
+- Searches both light DOM and shadow DOM recursively
+- Improved error handling to prevent breaking the update cycle
+- Errors in one property don't prevent others from rendering
+- Detection continues working even after errors occur
+- Maintains compatibility with all element structures
+
+# Test Elements Created (COMPLETED)
+
+## Created comprehensive test elements:
+1. **test-noprops** - Element with no @property decorators
+2. **test-complextypes** - Element with arrays, objects, dates, and complex nested data
+3. **test-withwrapper** - Element that uses dees-demowrapper in its demo
+4. **test-edgecases** - Element with edge cases (null, undefined, NaN, Infinity, circular refs)
+5. **test-nested** - Element with deeply nested structure to test recursive search
+
+These test various scenarios:
+- Properties panel handling of elements without properties
+- Complex data type display and editing
+- Element detection inside dees-demowrapper
+- Error handling for problematic values
+- Deep nesting and shadow DOM traversal
+
+# Fixed Demo Value Overwriting (COMPLETED)
+
+## Issue:
+Properties panel was overwriting values set by demo functions
+
+## Solution:
+1. Changed from attribute binding (`value=`) to property binding (`.value=`)
+2. This prevents browser from firing input events during initialization
+3. Added proper number parsing for number inputs
+4. Increased initial wait to 200ms for demo wrappers to complete
+5. Simplified select element handling to use property binding
