You can only customize the amount of dials, their colors, their spacing and their url, but not their aspect ratio, size, title, background image. The background image of the table are not automatically changed and a configuration box is affixed above the dialers even out of configuration mode. There is no option to exclude scrollbars, or to increase or decrease margins between the dials and the browser border. The imosibility of group tabs bothers, but is within the concept of being a clean addon, which can not be said of the other characteristics.

I want open urls in current tab. Please make it customable if it possible. And i want change background image to myself. Please make it customable if it possible

Great extension. I do agree with Morcas : it should be possible to reduce padding and to set Speed Dial for the new tab page (which can be achieved with "New Tab to about:home" [1] I guess, as a workaround)

Great to see a Speed Dial webextension, however, it would be even better if the addon could be set to Homepage/New Tab page and also support groups.

Edit: the left and right padding could use a setting for reducing the space used.

Verry Good
