As it is, on my 1440×900 @125% display, it comes up ok except when making a Pref change I see no Apply button or X to exit. I just guessed Esc would work, but no change in Prefs happened.
The change I went looking for is a toggle to mix Filenames and Foldernames by name Together rather than having all Folders on top with files below. I didn’t see this. MultiCommander can do this.
