Data-aggregating graphical user interfaces

The disclosed embodiments include computer-implemented devices and processes that generate, present, and manipulate data-aggregating graphical user interfaces. For example, a network-connected device may generate a first interface element representative of an obligation and may display, through a display unit, an graphical user interface that includes the first interface element and a plurality of second interface elements representative of time periods available for resolving the obligation. The network-connected device may receive, from an input unit, first input data indicative of a selection of the first interface element and second input data indicative of a movement of the selected first interface element from the first position to a second position within the interface. The network-connected device may associate the second position with a corresponding one of the second interface elements, and in response to the association, schedule the obligation for resolution during the time period represented by the corresponding second interface element.
