How to rename a plugin

I download a handful of plugins.
It has name on its qml file, but in both "Manage plugins" and the dropdown list from "Plugin", it has no names.
I don't see any place to rename it, either.
All of the names of the plugin I downloaded in dropdown list are "Run plugin() "
How to rename a plugin so I can know what it is when I use?

Note: I don't see any instruction on renaming a plugin in Handbook.
