scrollable piece palette panels

okay maybe I should experiment more before asking… but how do you get the panels in a piece palette to spread the counters out and let a user scroll through them instead of jamming them on top of one another?

I am checking “vertical layout” and leaving “fixed cell size” unchecked but this does not seem to do it.

and… never mind… “scrollable list” turns out it can hold pieces as well as sub-menus, so that does what I am looking for.
