I noticed that Powerlaunch said that the audience was intended to be developers, but the options available in the default setup for Powerlaunch are things that inherently interest end-users. I don't see why only developers would want to use the features available for Powerlaunch.

I would like to see a bunch of sample screens with explanations of what they do, and maybe the samples would be chosen so that typical users could blindly copy them to get what they want.

Powerlaunch is pretty popular, I think. But I can see that if Powerlaunch is about to be made obsolete by improvements in the default system, it might not be energy-efficient to put a lot of effort into explaining it.
