I'm a long-time The Unarchiver user. I noticed today that it can be installed and package-controlled by the App Store.
I'm a total App Store novice.
Normally The Unarchiver sits in /Applications/Utilities/. I didn't uninstall The Unarchiver before I installed it from the App Store.
Is there a way of determining that the version of The Unarchiver in /Applications/Utilities/ is the one from the App Store? Further, is there a way in the App Store to see all my software installed via the App Store at a glance?
