I personally think that the version number of apps, should not be isolated to the app store within the studio. I think developers should add or UNA.IO developers add fields to the apps within UNA.IO website here to show the latest and/or a history of app versions.
I get told often to upgrade to the latest when common issues like missing keys are there after install because often I find I am always on the latest update. And being able to come to UNA.IO just to confirm that I have the current updated version would be great. Who agrees?
