Johnson, thanks for replying to my issue.
Yes, that's my issue when ballooning. I have a machine with 200+ different parts on it, some duplicates & some unique. After I balloon all of the obvious and easy parts in the views I have on my drawing, there's always a handful at the end that I have to go back and forth with by opening and closing the parts list to see which items have the balloon icon there, and which ones don't.
It's very tedious, and a bit frustrating, when I have to go in and out of the parts list dialogue to see what items remained "unballooned".
Michael's ilogic rule, as well as niels suggestion are both good alternatives, but a floating parts list while you're ballooning would be great, especially if it would add the balloon symbols in the parts list column as you balloon your items.
