We actually wasn't sure.. how to handle the progress bar.. to jump 100% and do the job, as it now. Or stay at 0% and jump when the job is done. But in this case the jump won't be visible because user will be automatically redirected to a Finish page. I guess our users could write their opinions in this thread.
Sure, we will make the Wizard to populate selected servers, in one of the nearest bug fix builds.EDIT:Implemented in 2.5.69.1 build.
