Thank you for your bug report, your summary seems to mix different issues.
- dealing with minimized dialogs is an interesting case, gnome-shell decided to drop the minimize action from their ui, the recommended workflow there is to focus what you need rather than unfocs what you don't need, maybe unity should be doing the same
- double clicking on the launcher icon (or clicking once again after the software is focussed, which the first click does) will do an expose of the running instances of the softwares, that should make them easier to browser
- there is another bug which request for the expose feature to have titles by default which should make easier to distingish different instances of a same software
