 The implementation ensures that only feedback words with non-zero weights influence AI prompt generation, giving users precise control over theme influence.
 
-User notes:
-There are still UI problems with the sliders on the feedback weights.
-1. In the UI, with either mouse or keyboard it is impossible to get the value to 0. This is both visible in the graphical slider element as well as in the developer console watching the value be between 1 and 6. It should be possible to set to 0.
-2. The sliders should be much bigger, and preferably in a blocky style rather than a slim slider. Look into ways to drastically change the slider style. Make them huge - the width of the parent element and very thick.
+## Feedback Weight Slider Issues - Todo List
+
+### Issues Identified
+1. **Slider range problem**: Sliders only allow values 1-6, not 0-6 as intended
+2. **Slider appearance**: Sliders are too slim and need blocky, prominent styling
+
+### Todo Items
+1. **Fix slider range to allow value 0 (currently only 1-6 works)**
+   - Investigate why slider doesn't accept 0 value
+   - Check gradient background rendering for 0 position
+   - Ensure JavaScript handles 0 value correctly
+
+2. **Redesign slider appearance: make much bigger, width of parent element, very thick**
+   - Increase slider height significantly (e.g., 48px instead of 8px)
+   - Make slider take full width of parent container
+   - Use blocky, prominent styling instead of slim design
+
+3. **Change slider style to blocky style rather than slim slider**
+   - Consider alternative UI patterns (e.g., segmented buttons, large clickable blocks)
+   - Implement blocky visual design with clear boundaries
+   - Ensure touch-friendly sizing for mobile devices
+
+4. **Test slider functionality with mouse and keyboard to ensure 0-6 range works**
+   - Verify mouse dragging allows 0 value
+   - Test keyboard arrow key navigation
+   - Check visual feedback for all values (0-6)
+
+### Implementation Notes
+- Current slider uses `min="0"` and `max="6"` attributes but appears to not accept 0
+- Gradient background may not properly represent 0 position
+- Consider replacing range slider with alternative UI for better user experience
+- Ensure backward compatibility with existing weight data structure (0-6 range)
