Because a product can only be assigned to one Product Line, we have a flat product line that consists of ~20 products. When choosing a product from the top left filter, the products should be sorted in alphabetical order to allow me to quickly find the product I want.
You can create the order in which workspaces are displayed. You can sort your product hierarchy by going to Settings ⚙️ > Account > Configure workspaces. You can then drag and drop your products into the order that you want. When you hover over any workspace, the control to move it will appear.
