Maybe someone who has used it can tell us something. I hadn't used previously so I didn't get to see it work. I made 2 different browsers be the default, got the 2 btsregfile files and when I do the tray switch, the icon changes, but it doesn't seem to make the system refresh. i.e. when I start a browser and make it be the default (via the browser menu), usually I see the desktop icons refresh, and so forth. But when I use BTS, there's no obvious change.
