I think there is a disgreement between the versions. I am using 1.0-beta181 (Windows) and I do not see any checkbox in the preference tab to choose double-sized icons. See attached image below.?
Also, when I right-click on the icon of a station, there is no "Show Double-Sized Icon" in the Menu.
The only way it works for me is to select the station for tacking and then to tick the Double-Sized checkbox in the track list
