New Software Sources dialog doesn't show what software is installed by a repo
The new Software Sources dialog is great, but it no longer shows which apps are installed by a repo. Clicking on a repo name used to show a list of all apps that were installed by that repo (this even worked for Flatpak repos). Now, only the number of apps & addons installed by a repo is shown, which isn't all that useful to know without being able to check what exactly those apps (and if possible, addons) are.
