I guess this is actually a feature request, and not a bug report. Muon currently displays "progress report" of package actions like download, installation, upgrage etc. in its main window (replacing its contents with progress information) unlike the behavior of most other apps. I don't think this looks good as well as being inconsistent with other apps. Therefore, I'd like to suggest using a dialog window instead.

It seems we can consider Muon dead, and close this bug now.
