Which theme?

[zwn]

Hi,

I've recently purchased the genesis framework and magazine child theme and I'm very happy with it. I've been browsing the others themes and intend to purchase 2-3 more. My question is regarding some of the themes I like don't have all the features I would like. Is it possible to add slider etc for featured articles (similar to magazine), additional layout features (sidebar/content/sidebar) and landing page and call to actions to exiting themes that don;t have them already? Yes as always I want everything in one theme! Not really but I'd like some guidance as to the flexibility of the themes that would enable me to build on them without too much development, more plug and play.

Sorry if this is in the wrong place but it is a general theme question.

Cheers

Dave
