### Describe the improvement

I just noticed a warning in my updates for a dotnet installer that the installer host had changed and be careful the URL has not been hijacked. This is great.

But it would be even better to know what the installers host are when searching in discovery or updating without having to right click into package details all the time. Perhaps an option to enable an additional column showing this for those whom wish to know where their packages are coming from?

### Describe how this improvement could help users

Empower users to be more conscious about where their packages are coming from. Increases security awareness. Users may also choose difference sources if the information is more forthcoming.
