Yeah I am looking into removing the window frame much like the way KeyClone does it. So far though I am not yet successful.
You can resize and position, though you are still constrained to how mac does the resizing.

I used Plexer since the day he release it. Very fine app. I wanted the App positioning and resizing though, which is what motivated me to create my own. That and I am looking into multi computers support, especially Mac to PC for the next major version.
