## 2026-11-xx - Build 2611 - November 2026

* Resolved [#533](https://github.com/Krypton-Suite/Extended-Toolkit/issues/533), TreeGridView: Plus/Minus Sign Not Displayed in TreeGrid and Collapse/Expand Behaviors Broken
* New `Krypton.Toolkit.Suite.Extended.BottomSheet` module - Material-inspired bottom sheets for WinForms
- **Service API** - `KryptonBottomSheetManager` with `Open`, `OpenAsync`, `OpenNonModal`, and `DismissActive`; `KryptonBottomSheetRef` for `Dismiss()`, `AfterOpened`, `AfterDismissed`, and `AfterDismissedAsync()`
- **Configuration** - `KryptonBottomSheetConfig` with backdrop, height, focus, animation, and conflict options; global defaults via `KryptonBottomSheetDefaultOptions`

- **Batch Operations** - Replaced individual row insertions/removals with optimized batch operations
- **Expected Performance** - Reduced expansion time from ~6 seconds to ~0.5 seconds for 250 children (approximately 12x faster)
- **Implementation Details**:
- Added `SiteNodes()` method for batch inserting child nodes efficiently
- Added `UnSiteNodes()` method for batch removing child nodes and descendants
- Optimized insertion position calculation to avoid redundant calculations
- Improved removal order to prevent index shifting issues

* Resolved [#25](https://github.com/Krypton-Suite/Extended-Toolkit/issues/25), Can't add outlook grid group box control - Fixed language-related error when adding `KryptonOutlookGridGroupBox` control in Visual Studio designer. Replaced deprecated `LanguageManager.Instance.GetString()` calls with `KryptonOutlookGridLanguageManager.GeneralStrings` for DateInterval enum localization, eliminating dependency on resource files that could fail with EN/GB language settings.
* Resolved [#156](https://github.com/Krypton-Suite/Extended-Toolkit/issues/156), `KryptonOutlookGrid` Group Header graphic issue with scaling at 150%
* Implemented [#511](https://github.com/Krypton-Suite/Extended-Toolkit/issues/511), `KryptonMessageBoxExtended` Expandable Footer Feature
- **New Expandable Footer** - Similar to Windows TaskDialog, the message box now supports an expandable footer area
- **Collapsed/Expanded States** - Footer can start collapsed or expanded, with user toggle capability
- **Toggle Button** - "Show details" / "Hide details" button allows users to expand/collapse the footer
- **Multiple Content Types** - Footer supports three content types:
- **Text** (default) - Uses `KryptonWrapLabel` for simple text content
- **CheckBox** - Uses `KryptonCheckBox` for options like "Remember my choice"
- **RichTextBox** - Uses `KryptonRichTextBox` for formatted text with configurable height
- **Text** (default) - Uses `KryptonWrapLabel` for simple text content
- **CheckBox** - Uses `KryptonCheckBox` for options like "Remember my choice"
- **RichTextBox** - Uses `KryptonRichTextBox` for formatted text with configurable height
- **Configurable Content** - Developers can specify footer text content, content type, initial expanded state, and RichTextBox height
- **Automatic Sizing** - Form automatically adjusts size when footer is expanded/collapsed
- **New API Overloads** - Added `Show` method overloads with `footerText`, `footerExpanded`, `footerContentType`, and `footerRichTextBoxHeight` parameters
