that might get confusing if you had multiple tags on a source.
have you tried using filters and then filtering sources, so you could look at all sources belonging to a particular tag?
if this doesn't work for you, let me know why, and we can try making a sorting option that would get you what you wanted.
in general, i'ld like to rebuild the sources manager to be easier to use and more intuitive, so any thoughts on how you use the sources side bar would be very helpful.
