The ability to pass values, strings, variables, etc. to a console for debugging, along with a movable console window while the project is running :)
Any project, having a way to communicate information normally hidden or more obscure to myself when debugging projects without having to create a custom text object would be immensely helpful, and saves of having to create a new text object for each individual value that you want to see.
prints the given value into the console window, with the text color passed by the color value. the console window is active while the project is running and can be dragged around, or hidden offscreen when not needed. :]
console.log();, along with the many variations of
print(); in a variety of different languages.
As a side note- this could also be used for testing functions and value manipulation during a projects runtime.
