I followed that advice, and he kindly responded with this:

exactly what I was looking for (the overlays thing). Thank you everyone!
Afloat does in fact seem to be really cool. Thanks.
Now all I need is an app that can lock a window from "clicks" or gaining focus. That in combination with making it "float" and be transparent would be quite swell!
I think it would be neat to have a program that, when you hide a window, instead of making it disappear completely just makes it very transparent and "unclickable".
Is there such a thing?
Thanks,
Neri
