Package manager view with uploading, Installing different versions of the same package

As you know the package manager allows multiple versions of the same package to be installed. How would you find a list of version package installed and which one currently in use?

• The package manager only lists one entry & it would be the highest package version.
• There is an option called "Older Version" button in the package, upon clicking the list of versions of this package is shown. 

• The old version shows the list which was uploaded & not the one build in the same instance.
• The ordering control can be envisioned specifying, for example, a 1.0 by default and upping the last integer by one every time the package is built. So it goes like 1.0, 1.1, 1.2,......1.25, ...  

• Example: If you have 0.1, 0.2, 0.3, 0.4, 0.5, ......., .9, .10, .11, ......, 0.25 ...., Then version 0.11 is considered higher than version 0.9.

• Each package status indicates whether you have already downloaded, build, installed, etc.. It does not indicate which one is currently in use. Also, it is not possible because you can have the same content in a different package.
