Back in the days the Nautilus Browser had a "filter" text field directly above the category pane. One just had to click and enter the name and the list got filtered.
With more and more packages coming into an image this was very usefull in Nautilus since it allowed to filter the displayed. The Test runner now provides such a filter to easily find a category. I know there are groups, I know there is "Find Package" in the menu. But the filter was really helpful and avoided endless scrolling to initially search a category. Is it still available? Maybe as a Nautilus plugin? Thx T.
