After working out what does what, I'm quite happy with this, although I miss the old Speeddial. However, I hope that, in time, this will be as good as the Legacy Speeddial, and it seems from the other comments and responses here that the developer is working at speed to introduce some new "bells and whistles". The background refresh would be good, but appears to be impossible in the new FF architecture.

My main wish at the moment is to be able to resize thumbnails across the Dial Groups, and to make them smaller, which I would find easier to work with.
