Thank you very much @xpde for this tool.
However, now with that, we will need to change some themes and edit the file and rename it from panel.css to styles.css (this exists only for the Lightspace theme, so no need to alter your code, we will alter ours).
Keep in mind that Normal Themes (not Lightspace and Lite) will not work due to @xpde's script not searching for an icon_spritemap.css.
If you could do that, keeping in mind that console errors will be generated for lite and lightspace themes due to not having an icon_spritemap.css file (but the themes will load without problem), it would be nice.
