Is there a way to limit tag display of itemlists to within a set of categories?
Imagine a blog with tags as part of your K2 content - you only want to see tag listings from stuff in your blog, not the rest of your site.

SO when you click a tag on 'htc phones' you dont get items listings from another section of content which might be about your organization or recipes of the day.

I can see how you can pass a category id in the tag cloud module and adjust the itemlist model for tags. However this doesnt play nice with sef nor does it solve the larger issue of what items to show if you want it limited by multiple categories

Anyone have this itch?

Create a new menu item
Select Menu Item Type > K2 TAG
Select tag in Required Settings
Click on Basic Options > Filter categories

Hope that helps
