Hi, neat program. I just wanted to let you know that with a higher resolution webcam (eg 640x480), the main window is too small, so the video spills out behind the other components. Everything seems to work OK (well, except video recording) otherwise.
It would be nice if you could resize the window so you can see everything (resizing is nice also because if you're using a large screen font or something you can make the window larger so all the controls fit), or at least shrink the video to fit the window. Also you could have an option to set the device settings so you can choose a lower resolution (this might be nice in general also).
