Here is an article that I wrote that you might want to read:

Interesting. I have never seriously used F-Spot myself, so I did not
know this. Does Tracker make nao:Tags out of them? (All tags shown in
the tag view on the left are instances of nao:Tag.)

What you need is Tumbler:

You are lucky that it did not crash. :-) I did not test for that
eventuality for 0.4.

Good point. It would be very easy to filter them out, but there is a
problem. What if you create a new tag and want to attach it to a
photo. Since your newly created tag is not attached to a photo the
filter can block it and then you will not be able to attach it to

I have not paid too much thought to this, but if we can streamline our
tagging workflow and UI, I am sure we can come up with something. Do
you have any ideas?

One reason that life is complex is that it has a real part and an
imaginary part.
