Modifying breakpoint groups

On admin/config/media/breakpoints I can see my defined custom breakpoints, but not a list of the groups. Do you have a screen shot that shows where I should have a link to all breakpoint groups? The 'Add a new group' link doesn't list the existing groups either. It seems like I am missing something. Thanks.

I've attached a screenshot (Breakpoints_edit_screen.png) that shows my display of the screen at admin/config/media/breakpoints. This is consistent for both the release and dev forks of the breakpoint module. Note that it is missing the buttons at the top of the screen, and the links at the bottom.

Hi, I have this working now except for one small thing. In order to review and edit a breakpoint group, I have to manually go to the url (admin/config/media/breakpoints/groups/group_name). I don't see anything in the UI that displays the groups. So if this is working as designed perhaps this need should be added as a feature request?

Thanks. We have customized Rubik as our admin theme, so if that is all it is then I can live with it for now. Thanks for the great module!'

UPDATE: the latest release candidate for Rubik addresses the secondary tabs, so they are now available as drop downs in both Breakpoints and Picture modules. The problem was in the creation of Rubik subthemes where the secondary tabs were hard coded to appear only in the theme named Rubik. The issue is addressed here: https://drupal.org/node/1338316.
