Sometimes a "Download" button for software packages hosted in jamfcloud could be very helpful.
For example, if there's a package hosted where you don't have the sources any longer, but a newer version is needed. A simple "Download" button for one particular package would be enough to get the existing package and convert it to source via Composer.
Yes, there is an option to download the whole share via Jamf Admin, but this is not very handy. This option is already available for configuration profiles, so why not make it available for packages already hosted on HTTP distribution points?
