When opening production tab at a crafting station, we get a looooong list of options. If for example we're interested in refinement, there's a lot of scrolling to get there, or filter tool is useful.
But also very useful would be a button that toggles between "expand all" and "collapse all". That would, for example, let me collapse all, hit a specific category of weapon type or refinement etc, expand that category, and be where I want to be. That would be quick and pleasant.
