You can not hide home/account/option buttons on dial page and there is no numbering of dials and groups, or shortcuts to access them directly. But it is a very beautiful extension and the visual possibilities are diverse with colors gradient. For the future, it would be great to have more style options, such as right-angle corners, active tab of the same color as the active group, navigation between dials/groups by directional keys, backup of dials/settings, and option to do not overwrite default pages (newtab and home).
