The idea behind Options Constructor is to make settings windows modular and customizabable. You aren't forced to use whole premade settings window, instead you can drag&drop only these parts you need.
All widget parts used to construct your own settings window can be easily customized. Just make a copy of the desired widget and change its visual part and it is ready!
