When to display
This is an advanced feature that allows to define the exact time of background change. By default new background is applied after the word preceding it has been sung. You may change this by selecting When next word begins. It is also possible to define time offset to be applied -- for instance selecting '10' will cause the background to be changed ten seconds after the word has been sung (or 10 seconds before the next word will be sung, if When next word begins is selected).
