**Configure AMS Slot**

Manually configure AMS slots for third-party or generic filaments:
1. Hover over an AMS slot on the printer card
2. Click the menu button (:material-dots-vertical:) that appears
3. Select **Configure Slot**
4. Choose a filament preset from your Bambu Studio cloud presets
5. Select a matching K profile (pressure advance calibration)
6. Optionally set a custom color using the color picker
7. Click **Configure Slot** to apply

**Color Picker Features:**
- Enter custom hex codes or color names (e.g., "brown", "FF8800")
- Live preview of selected color
- Expandable color picker in Configure AMS Slot modal:
  - 8 basic colors shown by default
  - 24 additional colors available via expand button
- Tests for ConfigureAmsSlotModal component
- Tests for AMS change callback
- Updated README with AMS slot configuration feature
- Wiki documentation for Configure AMS Slot feature

- Multi plate issue where plate names showed incorrect. #93
- Items from Queue end up as "source" files in archive. #107
- Added env variable support to change network port. #108

+## [0.1.6b10] - 2026-01-20
+
+### New Features
+- **Expandable Color Picker** - Configure AMS Slot modal now has an expandable color palette:
+  - 8 basic colors shown by default (White, Black, Red, Blue, Green, Yellow, Orange, Gray)
+  - Click "+" to expand 24 additional colors (Cyan, Magenta, Purple, Pink, Brown, Beige, Navy, Teal, Lime, Gold, Silver, Maroon, Olive, Coral, Salmon, Turquoise, Violet, Indigo, Chocolate, Tan, Slate, Charcoal, Ivory, Cream)
+  - Click "-" to collapse back to basic colors
+
+### Fixed
+- **User preset AMS configuration** - Fixed user presets (inheriting from Bambu presets) showing empty fields in Bambu Studio after configuration:
+  - Now correctly derives `tray_info_idx` from the preset's `base_id` when `filament_id` is null
+  - User presets that inherit from Bambu presets (e.g., "# Overture Matte PLA @BBL H2D") now work correctly
+- **Faster AMS slot updates** - Frontend now updates immediately after configuring AMS slots:
+  - Added WebSocket broadcast to AMS change callback for instant UI updates
+  - Removed unnecessary delayed refetch that was causing slow updates
+
 ## [0.1.6b9] - 2026-01-19
