An undocumented? tip about UserInterface.messageBox

[nnikbin]

The Fusion 360 API help describes the first argument of UserInterface.messageBox Method as "The message text to display in the dialog." but in practice it is able to show formatted texts.

Just like TextBoxCommandInput.formattedText property, formatted text includes any html formatting that has been defined. For example, you can use basic html formatting such as Bold, Italic,  line break, and even use img tag to insert images. Please take a look at the following image:

Thank you @nnikbin 

Even if we should never rely on undocumented features until Autodesk make them official.
