Insert a dial that links to another group (or continuation page).

A dial that links to a different group would allow a way to 'paginate' the dials:

• [< Previous] (dials 10-20) [Next >]

It would also allow the front page to have top links from each group and link to the groups for more links:

• [Gmail] [Facebook] [More Social>]

You might also offer standard left/right arrows and brackets as default images to choose from.
