A method, apparatus, system, and signal-bearing medium that in an embodiment present a main view and at least one peek view of data. When the user selects to move the data from the main view to the peek view, a subset of data objects in the main view is selected based on an importance of the data objects and optionally based on the size of the peek view. The subset is copied to the peek view, and the peek view is dynamically updated when the data objects are updated. In this way, the user can monitor changes to the peek view while working on other data in the main view.
