I observed that a web page title for questions asked here is generated by the first tag + full question. However the ordering for the tags is fixed once added, unless one removes all tag and re-add them one by one, it stays as-is.
Some tags in the middle of the list might not be a very good categorisation of the question, yet they get displayed in the web page title (title attribute of an HTML page) when a user removes the first tag. So is it OK to add a feature to reorder the list of tags, or to let the user specify which tag is the main one?
