currently when you add lots of dials they become smaller and smaller until you dont see anything. (at 20rows 20 columns) because of that im waiting for fixed-sized dials and scroll-bar layout (infinite rows support) just like in opera browser. thanks for the addon and hope you can add this features soon.
It's planned and I really hope it will come by the end the of summer holiday.
But instead of using many dials in one page, you should group them in the groups (like files in folders). You will be still able to access them fast through group-dials (dial pointing to a group) - no need to use the small tabs on the top. See my introduction video where I'm creating a group Work for work-related dials: https://www.youtube.com/watch?v=wvT4w-R8hJU
