I have no idea if you're still active on this, it works flawless, so there might just be no need to change anything.
It's more of a feature request than a bug: sometimes the clear-event coincides with the completion of a download so that there's now time to click on it to open the file.
It would be nice if there would be an option to change the behavior so that it clears the bar 10 seconds after the last active download finishes.
