Not sure if it is my configuration or not, but when I navigate up the folder tree using the 'Go Up' button, Directory Opus selects the previous folder that I've just left. However, if instead, I use the appropriate button in the breadcrumb address bar it doesn't select anything and just shows me the folder.
File Explorer remembers and selects the correct folder if navigating by breadcrumb which is great if you want to go back 3 or folders in one click but still know where you are in the list...
