Only show or hide? Or more complex restriction options available?

Gday ??
Does your plugin only show OR hide?
Or can it also include more complex scenarios?

Is it possible to restrict clicking on a widget and getting access if user is non-paying user?
For example all users can see online members and popular members in sidebar widget (either horizontally or vertically displayed) like in Facebook. But if a user is a free user he cannot click on those little round online members in the sidebar widget. If a user is paying member they can click and acces that particular online mebers profile page though.

Any suggestions?
