Currently you always have to choose kind of short names for styles. In combination with sometimes wrong preview of the style it is kinda limited of usage.
You cannot have e.g. four styles where the first few words are the same and they may look the same in the preview, but differ slightly, since you cannot differentiate it without knowing the full name ("background_dark", "background_dark_invisible_text", "background_dark_white_border", "background_dark_title", etc). If the style name could be shown on hovering over the style it would be so much easier to provide an extensive stylesheet.
