1. Rationale

Organizing feeds into tree-like structure using (possibly nested) categories helps with handling large feed collections.

2. User interface

2.1. Feed list

The following operations should be possible directly on feed list:

• adding new category
• removing existing category
• reordering categories (using drag and drop)
• assigning feed to categories (using drag and drop)

2.2. Categories tab in Preferences

I don't think it's a good idea to place category management in Preferences because UI for it is just too big and complex to fit nicely in Preferences dialog.

2.3. Category Manager / Feed Organizer

Instead of placing category management in Preferences we could gather this functionality in a separate dialog. Moreover, there we could allow not only category editing but also advanced feed organizing - stuff like assigning multiple feeds to a category could be handled via Feed Organizer.

See how this is solved in GreatNews.
