You can have more than one storage location for clothes; put items that wouldn’t fit on this rack in a closet.

in the video on the Kickstarter she show how you can hang pants

Yeah, I normally put a number of items through the coat hanger and the hinge, here, would prevent that.

I feel like it should come with some clips on the bottom for attaching items like trousers and other odd-shaped garments.

I normally fold my pants in half vertically and over the hanger. How do you normally do this?

Some examples here, most of which should work with her hanger size:

I fold the legs together (fold along the zipper, basically) and put them through the hole, which folds them again roughly above the knee.

There's very little room left on the hangar when I do that. Just like in that site's method.

So given a regular hanger will have ~10% of the hanger left empty with pants on it, and the new hanger cuts the continuous length down by 40%, I don't see how it'll be wide enough. Maybe her small person pants fit, but it doesn't seem like mine would.

For others' reference: the "one leg over, then the other leg over the other way" is how you hang a bespoke suit's pants. No special hanger needed, the cloth's opposite drag provides enough friction to keep it on. The hangar for the cuffed pants is good for keeping the cuffs in shape (but who wears cuffs?)

I think pants would work, if you put them in legs first.
