Labeled feeds

Hi!
I've managed to tidy up the code a bit.

I'm aware that the dot-based nomenclature I've chosen is not so pretty but I still find useful the overall functionality. Anyhow check it out and let me know if you would like something different.

The config I've used is the following:
```
