When launched, the application displays the “Catalog” view.
This view consists of 3 panels:
1st panel: The Catalog panel showing your catalog’s product categories
2nd panel: The Products panel listing the products in the selected category
3rd panel: The Properties panel showing the properties of the selected product
The selection procedure is fairly simple: reading from left to right, just select a category and then a product to display its properties.

The width of each panel is recorded in a cookie so your workspace is saved from one session to the next.
