Not A Bad Portrait Touch Up Piece of Software for free

This is not a bad piece of software for touching up portraits. A few things I would love to see in this software.
1. I have a magic mouse and it would be nice if you could change the size of the brush by swiping the magic mouse up or down.
2. To be able to see the changes in real time as you move the slider rather than waiting for it to update after you move the sliders.
3. After you do make an adjustment and are finished you have to hit the apply button..
4. Before and after views
5. You have no control of white balance, saturation, sharpening..etc.

But for it being free, its not to bad
