How To Make Responsive Teaser Layout In Spark?

changing priority as support requests aren't considered major.

Can you explain your request in a little bit more detail? Have you reviewed the videos posted about the components of the distribution on the project page?

The Spark layout builder is dependent on Panels, which is what provides the content placement (regions) capabilities as well as in-place editing for the layout content placement on the front-end and path assignment for layout-content combinations through page manager. I honestly have not tried putting display suite on top of this setup, but the layout builder will definitely not work without panels (and not be useful without page manager).

Panels/Panelizer works well with Views, however not regular regions, that is true. We needed to pick a system we can integrate with. Unfortunately systems like panels and spaces/context don't use the same kind of backend solution to provide for layouting. It is theoretically possible that the layout builder would generate phptemplate files but then those are not exposable to the theme system if they are not in the theme, so we'd need to impose a specific frontend theme on you that supports our outside-injected layouts. We needed to pick which limitations we want to accept. I think working with Panels turned out to be good for us, especially with the growing popularity and cohesion of the system with Panopoly (http://drupal.org/project/panopoly).

Superb!

The standard grid display uses tables, which is easy to generate programatically but murder to reshuffle on the fly. This one is div-and-CSS based, which allows you to control more of the behavior using media queries.
