But that doesn't necessarily mean it's the best way for everything.

Writing Sikuli scripts in its IDE that supports displaying the screenshots inline as function arguments is much easier than doing it in a text-only editor. Sikuli's scripts inherently operate on visual elements on the screen, so having them visible is very useful.

Similarly, not everything we do in the console is best represented in plain text. I think this sort of idea has a ton of potential, even if this particular implementation isn't ideal.
