The background color of items in the main window application list are used to convey the information for the state of an app (Verified Certificate, Unverified, Unregistered application, Windows Store App, Missing Uninstaller).
Conveying information solely through colors is unpractical for colorblind people.
While a Colorblind Mode is provided, it would be useful to provide the same information as a regular text column too.
It could be something like a "Status" column, just behind "System Component".
This would also provide a quality of life improvement by allowing to sort apps by this column.
