Abstract: Features for adaptation and control of a graphical user interface (GUI) and GUI functionality are disclosed herein. In an example, a user interface control is provided in a GUI to receive interaction from a user, which is provided in an enabled state to offer functionality for the user to attempt an initial commerce action with a constrained item. The user interface control is changed from the enabled state to a disabled state, in response to receipt of the interaction from the user, and a delay time period is calculated for the disabled state (with the delay time period being uniquely calculated for the user). The user interface control is changed from the disabled state to the enabled state, upon expiration of the delay time period, and the enabled state of the user interface control provides functionality for the user to perform a commerce action with the constrained item.
