Plugin to sort items by subject?

Is there a plugin that allows users to sort items by the "subject" Dublin Core field, and browse available subjects? If not, I'll write one. I just wanted to make sure there wasn't already something that does this.

Not entirely sure, but Search By Metadata might come close to your needs.

When viewing an item, it'll make fields you configure clickable to search on the metadata displayed.

Sounds possible, though, that you want something that doesn't start with a particular item?

If that's the case, it'd call for maybe something in navigation or a plugin that builds off of the same idea, and hopefully borrows code!

Hope that helps
