Re: multimedia columns in list view

["Giacomo Bordiga" <gbordiga gmail com>]

Maybe I'm coming too late, but i wrote a nautilus extension that does
the same thing. It is only a draft, a test. It is written in python
and uses mutagen python module, so you need to have installed
python-nautilus (nautilus extensions python bindings) and
python-mutagen. After that just copy the script to
~/.nautilus/python-extensions, restart nautilus and you are done.

It is much less code (33 lines) and, i think, much less resources are
needed (over a 371 mp3 folder the time to get and display album,
artist and title is less than a second on a 2.2Ghz).
