thanks for your question.
Unfortunately I don't really understand what you mean.
What exactly are you expecting to show up where?
Can you clarify your problem a little bit, maybe?
You are talking about the Tablesorter. This is not a WordPress plugin though. It is more or less a plugin (or better add-on) to my WordPress plugin WP-Table Reloaded. Therefore only WP-Table Reloaded will show up in the WP list of plugins. Is that what you were refering to?
