Comment # 5 on bug 973590 from Martin Vidner

As we can see on the screenshots, on other architectures/bootloaders that space
is occupied by various options. But I don't understand either why some of them
are to the right of the Boot Loader combo and some are below it.

One option is to replace the missing option frame to the right with a HStretch
so that the ComboBox is aligned left, another option is also to move the
[missing] option frame *below* the combo.

Josef, can you please explain this?
