Adds a button to the custom section <section-name> on the Screen Console Manager HUD. The section must have previously been created using add-section. <icon> should be the UUID for a white-and-transparent texture not exceeding 128x128 px. <command ...> may be multiple words, space-separated; in the event the button is pressed, it will be sent as a 1 COMMAND system command message to the controller with the console as the executing user.

If add-button fails, the device will be sent an add-button-fail message; otherwise it will receive add-button-confirm.

There is no way to remove or modify a button or section from the Screen Console Manager once it has been added.

Sent by Screen Console Manager to another device. Indicates that a button was successfully added to the section <section-name> by that device using add-button.

Sent by Screen Console Manager to another device. Indicates that a button could not be added to the section <section-name> by that device using add-button. This error message is sent only if the section is already full; no error is produced if the section does not exist. If you are uncertain as to whether the section exists or not, send add-section again; the message will be ignored if the section already exists.

Sent from any device to the Screen Console Manager (_screen) HUD. Adds a new section; the HUD will reply with add-section-confirm. <name> should be a short unique identifier, such as the device address; <width> is the number of icons that the device intends to display. Not supported by the Native Console (_native) HUD; see icon-q instead.

It is not possible to add custom gauges or meters to the Screen HUD. There is no way to remove or modify a button or section from the Screen Console Manager once it has been added.

Sent from controller to _console-screen HUD. The system has a new config file to send; delete the old one. This occurs whenever the _console-config notecard within the controller has a different inventory asset UUID from the last version that was sent to the console. After deleting its copy of the configuration file, the HUD will send config-q to request a replacement.
