WMP Plugin not showing up in the plugin panel?

Must be something you have installed or custom code causing the issue, it appears just fine for me.

enter image description here

If your question was actually why there’s no additional menu item on the admin side then the answer would be because not every plugin has an admin page, some provide configuration options, others just do something with no configurable options(depends on the intent of the author i suppose).

Hope i could help in any case..
