Abstract: Systems, methods, and devices for a graphical user interface (GUI) builder for a heads-up display. A user may interface with the GUI builder to create a profile. The profile comprises a logical ordering of one or more screens, with each screen comprising at least one widget. The widgets may be configured to display data on the screen and may be configurable by the user. Profiles may be shared with other users. A software development kit may be provided for developing custom widgets. The heads-up display may be on a night vision device.
