Dock in Lion FullScreen I would like to know if there is a way to have the dock always there when running an App fullscreen in lion?
It is very unlikely that Apple will ever support this request officially, as it would go against their whole "full-screen" philosophy. However, it ought to be possible to create a SIMBL hack which achieves it.

If you do want the dock visible when using an app - perhaps the best solution is not to use fullscreen, but simply make the app window large by using the green traffic light button or dragging the edges.
