side by side repository selection in content view
As an enhancement to the Web UI, I would change the view of the repository selection within a side by side comparison (maybe even drag and drop field), instead of having to switch tabs, wait to load, and switch back.
Go to the Foreman Webinterface -> Content -> Content Views
Select a Content View -> Yum Content -> Repositories
Now you get 2 tabs under Repository Selection
I would expect an side by side list of the repositories, left the selected, right side the available.
Benefits: Greater overview, faster workflow for adding repos, as I do not need to switch tabs to compare.
