Comment 4 for bug 186582

'Incomplete' just means that we're waiting to hear back from you. If you had gone and joined another bug, then that status just means this one would have faded away into the sunset after 60 days. It's not a judgment, it's just a way to control 'bloat' in the bug tracker... Anyhow, I've set it back to 'New', since I can't confirm the error you're seeing (I don't get any error on Linux in recent development snapshot--the effect just fails silently on non-path objects).

The reason I made the suggestion that you try to find another bug to add your thoughts is because sometimes the best way to get a feature improved is to try to get a lively discussion going all in one place. In particular, this extension has had a lot of complaints about usability, but they're in bug reports that are spread out all over the place. I think that the problem is that the effect " is not intuitive, to say the least", as mentioned in the bug I referred you to, and that your suggestion is a good one. (It's not quite a bug, though, since the effect is documented as only working on paths...)
