Easy; for something like that you might want a simple UI element that flashes on/off as appropriate. For a slightly more sophisticated feedback, perhaps something that glows brighter or more intense colours as the rate changes, or even a good old VU meter style widget? Even more info needed? How about a rate-sensitive meter and an associated actual log view that can be checked, reviewed, saved to file, whatever?

I've been trying to keep the idea of a faintly exception related mechanism separate from whatever UI widget is best for any particular use; I hope that particular tree hasn't got lost in the woods of this long list of messages. A pop-up progress bar is only one of many options that would be useful.
