One way to greatly increase the flexibility of displaying categories that seems relatively simple would be to allow limitation of the display of categories by parent. It seems the obvious next step in having nested categories.
For example, in an antiquities site I have three top-level categories, “cultures”, “materials” and “object types” and want to be able to display these as three separate columns. Rather than play with PHP and tables/floating divs, it would be nice to just be able to make three calls of the exp:weblog:categories tag, each with a different parent= parameter.
One more thing: it should have a display-parent switch, as I may just want to list my cultures or materials rather than state “Cultures” and “Materials” at the top.
