Abstract: Embodiments of the invention relate generally to an interstitial panel in an interface for navigating content. In various embodiments, methods and computer readable media can render content in response to selections in navigational panels without transitioning away from content in a content panel. In one embodiment, a method includes rendering content from multiple sources of content in a first interface portion, presenting a representation in a second interface portion for a pool of content that forms a subset of the multiple sources of the content, and presenting descriptors in a third interface portion for the pool of content. Presenting the representation and the descriptors can occur simultaneous (or nearly simultaneous) to rendering of the content from the multiple sources. In another embodiment, the first, second, and third interface portions can include a content panel, an application navigation panel and an interstitial navigation panel.
