CAWAS  Very nice little app that should even be built in the System Preferences in Leopard (Mac OS 10.5).

I'm missing few things:

- changing shortcut for brightness display

- saving customized preferences to somehow export in another machine (keep in sync)... although this should work together with some other app instead of trying to built it in.

- Open source! I'm trying for quite some time to know how this is done, and I'd love just to know how it's done, and why did I need a software to get it done. But I guess for this item I'll have to keep investing on my research.

Other than that, does pretty much everything I wanted to and couldn't do with keyboard preferences. Specially nice "Floater" feature. You should sell this to apple integrate into snow leopard or maybe the next OS. :P
