Contributions summary:Mark primarily contributed to the Android-specific component of the `bottomsheet` repository. Their work included modifying the `IntentPickerSheetView` to handle column numbers, improve the click handling API, and implement lazy loading for icons. They also addressed integration issues with the YouTube player and added features such as handling sheet display when another sheet is already present, and custom column width configuration for multiple sheet types. These changes demonstrate a focus on improving the usability and functionality of the bottom sheet component.
