Copy paste Checked box text to next sheet

3 things i want your help for:-

1. If I will click on “uncheck all” button, then all check boxes should get unchecked.
2. If I will click on “Export Selection to Next Sheet” button then the selected items in column D only should be copied and pasted to next sheet in cell C3 Without any empty rows in between.
3. If we click on check boxes in column B, then all the check boxes under that set should get checked or unchecked (Like if check box in cell B2 is checked/unchecked then all the check boxes in range C3:C6 should be checked or unchecked).

Below is the link for the sample file. It would be highly helpful if you can add the code to the below workbook.
