and the final html with modified links is written.

On a new Download, you can press cancel (once only) it will finish the current
downloads, update whatever is necessary and stop. Check what you got, adjust
parameters, and Continue just fine.

Update and Cancel is broken. Anything not yet processed gets lost and the
following Update will redownload everything else.  Instead, just pause and
resume. Don't kill the program, hibernate (not shutdown.)
