If you need a separate new menu window use:
```cpp
viewer.ngui->addNewWindow(Eigen::Vector2i(220,10),"New Window");
```
You can also switch between different orientation of the layout:
```cpp
// horizontal alignment
viewer.ngui->addNewGroup("New Group",nanogui::FormScreen::Layout::Horizontal);
viewer.ngui->addButton("Print Test1",[](){ cout << "Test1\n"; });
viewer.ngui->addButton("Print Test2",[](){ cout << "Test2\n"; });
// vertical alignment
viewer.ngui->setCurrentLayout(nanogui::FormScreen::Layout::Vertical);
viewer.ngui->addVariable(boolVariable,"bool");
viewer.ngui->addVariable(floatVariable,"float");
viewer.ngui->addWindow(Eigen::Vector2i(220,10),"New Window");
```
If you do not want to expose variables directly but rather use the get/set functionality:
```cpp
viewer.ngui->addVariable([&](bool val) {
boolVariable = val; // set
// ... or using a custom callback
viewer.ngui->addVariable<bool>("bool",[&](bool val) {
boolVariable = val; // setter
},[&]() {
return boolVariable; // get
},"bool",true);
return boolVariable; // getter
});
```
