Ah, yes, I do recall seeing this.  But, I wouldn't really call this a
re-try facility, because if 1 out of 100 packages downloaded with errors,
the "re-try" will pull all 100 packages all over again.  A far cry from
ideal, I'd say :) This is why I was proposing something much more
realtime.  Such that during the download of a package, if an error
occurs, it prompts you to re-try right there any then.  A further
optimization would be to have a checkbox to automagicaly do a re-try up
to a certain number of times.

Except that they end up either having to craft the commands to pull only
those package directories they really want, or pull the whole she-bang.
Again, not idea.  If I get time, I'll look at Setup and see what it might
take to add this "feature" (no guarantees, though).

You're welcome :)
