A computer readable storage medium storing at least one program, the at least one program comprising instructions to, when executed by at least one processor (110, 2124, 2230) of an electronic device (100, 2100, 2210) included within a vehicle and including a display, cause the electronic device (100, 2100, 2210) to: while executing a first application and a second application, display an execution screen (310, 2310) of the first application within a first partial area, and display a widget of the second application including a first executable element and a second executable element, and a first executable object to indicate the first application, within a second partial area located adjacent to the first partial area, the first partial area and the second partial area forming a display area of the display; based on receiving (2259; 2261, Yes) a first user input for the first executable element of the widget of the second application while displaying the execution screen (310, 2310) of the first application within the first partial area and displaying the widget of the second application and the first executable object within the second partial area, display an execution screen of the second application switched from the execution screen (310, 2310) of the first application within the first partial area and display within the second partial area a widget of the first application switched from the first executable object and a second executable object to indicate the second application, being switched from the widget of the second application; and based on receiving (2259; 2261, No) a second user input for the second executable element of the widget of the second application while displaying the execution screen (310, 2310) of the first application within the first partial area and displaying the widget of the second application and the first executable object within the second partial area, display at least one visual item available through the second executable element within an area extending from the widget of the second application, in an overlapping manner, on the execution screen (310, 2310) of the first application displayed within the first partial area. while executing a first application and a second application, display an execution screen (310, 2310) of the first application within a first partial area, and display a widget of the second application including a first executable element and a second executable element, and a first executable object to indicate the first application, within a second partial area located adjacent to the first partial area, the first partial area and the second partial area forming a display area of the display; based on receiving (2259; 2261, Yes) a first user input for the first executable element of the widget of the second application while displaying the execution screen (310, 2310) of the first application within the first partial area and displaying the widget of the second application and the first executable object within the second partial area, display an execution screen of the second application switched from the execution screen (310, 2310) of the first application within the first partial area and display within the second partial area a widget of the first application switched from the first executable object and a second executable object to indicate the second application, being switched from the widget of the second application; and based on receiving (2259; 2261, No) a second user input for the second executable element of the widget of the second application while displaying the execution screen (310, 2310) of the first application within the first partial area and displaying the widget of the second application and the first executable object within the second partial area, display at least one visual item available through the second executable element within an area extending from the widget of the second application, in an overlapping manner, on the execution screen (310, 2310) of the first application displayed within the first partial area.
