Wow, what a great tool! Thank you!
Two things:
There are some moments when OSD is constantly blinking almost every second (no matter is click-through on or off), which is kinda annoying. Didn't figure out what causes this. Windows 7, aero disabled.
I'm sure you know that device finder doesn't really show the correct device numbers

And minor things:
It would be good if password was stored like this: "*************".
Maybe would be also good to let the user to hide OSD when he needs to. Like, some checkbox "show OSD" or something.
Desktop lag is more significant compared to the usual phoenix with the same settings.
