With the container layer you can group layers together and move, rotate and scale them as one.
Choose LAYER > Add layer > Add container layer... to create a new container layer.
The new container layer can be selected from the layers dropdown to make it the active layer.
The installer comes with shows demonstrating the possibilities of the container layer. Choose FILE > Open show... and select a show from the BluffTitler/Media/Shows/Container folder.
To quickly switch between your own shows and the ones that come with the installer, click on the Personal and App buttons in the upper right corner of the file dialog.
The container layer does not render anything, it only groups layers together. And when you delete a container layer, all attached layers are deleted as well.
It is useful in situations where you would like to animate several layers at the same time. When you move, rotate or scale a container layer, all layers that are attached to this container layer are automatically moved, rotated and scaled as well.
Attach a new layer to a container by making the container layer the active layer and choosing a submenu of the LAYER > Attach layer menu.
Choose LAYER > Attach layer > Attach active layer to a container to attach an existing layer to a container.
Choose LAYER > Detach active layer from container to detach the active layer from its container.
A container can be attached to another container: make the container the active layer and choose LAYER > Add layer > Add container layer.
