Icons in Category view/Sort by colour?

Hi all,

I was thinking about ways to use a single Discourse more effectively with multiple communities. I know we can set an icon for a category, but if we could have it show the icon in the category listing it would make it much easier for people to skim to look for their team.

On that note, whether we can use icons or not, we try to use the same colour to group things for similar teams (or we should). Can we make the category page sort by colour/icon?

Do you guys think these are useful suggestions?
