Potential Feature: XML view

[snwh]

While the visual optimization view is nice, it may be worthwhile having a view switcher to allow seeing the markup/xml optimizations as well as the visual.

Do you have a use case in mind?

The point of svgo is to produce small and optimized XML output so I'm not sure that this would be very useful as it'll be unreadable to humans.

Likely not for large illustrations but of you are designing simple SVG icons for example, which might only be a couple objects, it is useful to see the XML in case there are errors or if the optimization was overly aggressive which may affect how they are displayed on the web or what not.

I think a markup/xml preview could do some basic whitespace formatting. Removing unnecessary whitespace doesn't need to be included in a markup preview because it's such a simple operation. To avoid confusion, a small hint could be added, such as "For readability, the preview does not include whitespace optimization".
