Image forming apparatus, method of controlling display, and recording medium

An image forming apparatus installed with at least one first application, the image forming apparatus comprising:

• processing circuitry configured to:
• display, using a program, a plurality of first setting screens for setting the at least one first application and to receive a first input of a first setting value of the at least one first application,
• store first information to display the plurality of first setting screens for setting the first application,
• install a second application on the image forming apparatus, and
• add, in response to installation of the second application, second information used for displaying at least one second setting screen for setting the second application to a memory without changing the system program, the second information including location information indicating a location of the at least one second setting screen in a screen transition among the plurality of first setting screens, wherein
• the processing circuitry is further configured to, using the system program control the screen transition among the plurality of first setting screens and the at least one second setting screen to be displayed, based on the location information of the second information added to the memory, the second setting screen to be used for receiving a second input of a second setting value corresponding to the second application,
• the system program provides a setting function which reads setting information from the memory to generate and display the plurality of first setting screens and the at least one second setting screen,
• wherein the adding second information used for displaying at least one second setting screen for setting the second application to a memory includes setting a plurality of locations for a single setting value and setting information.
