This plugin is provided for CJK users.
CJK users usually have some CJK characters in theirs title. When generating slug with title, it will be a bit terrible.
This plugin can change omit title from url. For example, you have a discussion which title is "欢迎使用Flarum", You will get a url like "/d/233" instead of "/d/233-Flarum".
Note: this is only a front-end change.
Feel free to open any issues if you have questions.
