Show package name in window title when opening package file

[jmairboeck]

It would be helpful if the package name was added to the window title of the HaikuDepot window when opening a package file, so that multiple such windows can be distinguished by the Deskbar menu or Twitcher.

Since you can have different versions of a package in different places, an indication of the package location could be nice too.

In same spirit, it could be nice to know if a package is active or not.

Something like [System/Home] [Package_Name] [Active]

I've put the package name and version into the window title. I think putting more is a bit too much; it's in the window's content except for the path. It may be a good idea to open a new ticket to show the path there somewhere?
