Yep. And it's exactly the right tool. I take suggestions for any more

Yes, this is exactly what I mean. Sorry I was unclear.

I don't know. Does anyone really have 1000 icons on their desktop? I could
do no icons and 20 icons. That might be interesting. Alternatively if
number of desktop icons has no real impact, then I report that.

It would also depend on which tool each distribution uses. I *think* Sues
uses beagle and Ubuntu and Fedora uses trackerd. If so, I would expect

It occurs to me it would also matter if the folder has been previously
visited and had the icons made, or if it's a new folder (like a memorystick)
that needs to get it's icons made.
This could also be interesting, even though updating

Thanks for the suggestions. I'd love to hear more suggestions from you (or
