That's pretty cool! Are you also planning to add a utility for storing alignments as textgrid files?

I think we can add several utilities: one to convert snowfall alignments to ctm, another to text grid.

The above example contains only one tier, phones. We can also add another tier, words. And they can be visualized together in a single figure.
