The present invention extends to methods, systems, and computer program products for visually manipulating instance collections. Items presenters present data collections along with custom designers for each data element in the data collections. The customer designers also permit data elements in the collection to be edited in situ. Items presenters maintain data elements in a position aware fashion. Thus, data elements can be inserted into (potentially at a specified location) and deleted from an items presenter to corresponding add and delete the data elements from a data collection. Data elements can be visually moved from an items presenter in one root user interface to an items presenter in another root user interface to corresponding move the data elements between corresponding data collections
