Is a known (SEO) issue that if You save a draft post without title, the post_name or slug is immediately saved with the post id.
Later, when You finish your post and put some title, the slug doesn’t change; neither also when your slug preference is %postname%.
So, what if we include the following function to rewrite the slug before publishing the post?

This plugin allows you to use longer URLs (permalinks), by allowing much more characters in your titles and slug. The important is that this is done in a way that is future compatible with WordPress core updates. 
There is a 200 characters limitation on WordPress core nowadays and this limit is raised to 3000 with the plugin. 
Plugin is always extending the current WordPress core code – your long URLs will work even after WordPress core updates. 
This plugin is really useful especially in non-latin slugs because of the required url escaping that increases the length of your permalinks a lot.
