There's currently an API for input editors — to customize the widget that pops up when you double-click on an input port to edit the port's constant value.
This feature request is to add an API for input viewers — to customize how input port data is displayed in a constant flag and how input/output port data is displayed in a port popover. This API would be available to any node developers, but just to give a sense of it, here are a couple of examples of how I envision it being used by Team Vuo:
- For Image ports, display a preview of the image in port popovers.
- For Font ports, make the text font and color in the constant flag match the chosen font.
