I was thinking mine is underused but in the past year has been used for pesto, risotto, soup, emulsion sauces (bernaise hollandaise), making rice and chick pea flours, brandy butter, gazpacho, icing, making icing sugar. But I could use it more often.
Which attachment are you using to make dough?
Edit
Just discovered the dough function on my Thermomix. That’ll be useful when I am feeling lazy.
