The general idea is that a plugin would be able to add additional visual effects/functionality to the tasks performed by the window manager without adding new dependencies to the core. Possible extensions might include: 1. desktop chooser plugin, similar to 3ddesk 2. full-screen application chooser, similar to expocity or komposeI think what you're looking for is libwnck. Xav |
