"编辑摘要追加"，顾名思义，追加编辑摘要。由于使用新版源代码编辑器时，在预览后常常忘记加入编辑摘要，所以有这个想法。
其只能对自己的编辑追加编辑摘要。
"Edit summary supplement"——When using the source editor, I always forget to add edit summary after previewing, so I have this idea.
The tool can enable user to add edit summary when that happened, but only for one's own edit.
