Sites like newspapers often have per-topic feeds in addition to the global one. I subscribe to multiple of those to avoid sports :P

Sometimes I'm not in the mood for politics, so I'd like to sequester all newspapers into a folder.

Now I need nested folders.

One feed can be placed in several folders. I.e. folder is actually a tag. So you could try to organize feeds that way. Most apps should support feed in several folders.

But still I don't like additional complexity of managing nested folders. Too few people have asked about it.

You could make feeds in subfolders available in higher level folders. For example I could have a folder News w/ subfolders like Slashdot, Local Newspaper, etc.

If I select News, I will see the contents of the subfolders as well and the mobile apps will only see the top level folders.

I'm not planning it yet. The problem with nested folders is that mobile apps doesn't support them and not many people has requested nested folders.

Any update on the idea of nested folders?

Yes, nested folders.

I don't see tags in commafeed. Do you mean nested folders?
