This is an extension to save and optimize SVG files with SVGO at Inkscape.
The default Inkscape SVG files require a lot of inkscape metadata for edition purposes since SVG is the default file extension at inkscape. Using SVGO we can remove a lot of redundant and useless information such as editor metadata, comments, hidden elements, default or non-optimal values and other stuff that can be safely removed or converted without affecting SVG rendering result.
SVGO is a very active plugin in continuous development.
