Each thread is presented sorted by Code, with the ability to view a detail page which tells you the number, the colour name, a sample of the colour, view and modify the 'ownership status' and view and adjust the amount you own/need to buy. 4 buttons down the bottom of the application allow you to easily filter out/in threads based upon 'ownership status', allowing you to view only the ones you need to buy, or own easily. A search feature allows you to find threads by their Code. By setting the Mode on the threads you need to buy to "Need to buy" and then selecting "Don't", "Do" and "Bobbin" so they are in the deselected state, you will be left with a list of the threads you need to buy, hence forming a Shopping List.
