HI I'm in the web just today, and see this dock differential. *-*
Well as the title suggests, it could be implemented wanted the option to change the direction of rotation of the dock.
When I downloaded the program I thought, "This should use C + + or another "hardcore" language, but again I was caught by WPF.
I had tried to create a dock in this style but with Windows Forms (C #) but realized that would require a very good logic.
Anyway my suggestion is just to change the rotation of the dock to another sense
Thank you for your attention =)
Sorry my english it was done by Google Translate D:
