At present, to remove a tattoo with the SkinWriter you have to enter a single space character (' '), which then overwrites the current tattoo. If you try to just enter nothing at all, you get the message that you need to enter -something-.
The issue with this is it leaves an extra space between nakeds, which can just look a bit off. Would it be possible to either add a new command to the SkinWriter that removes the selected slot instead of adding, or make it so that there's no check for content when you enter a tattoo (ie, so that you could just press enter for an empty string)?
