List Installed Apps?

[Clete2]

Is there a way to get the Mac App Store to list already installed apps? I want to see what it detects.

I'm wondering the same, actually. Doesn't seem to auto-detect apps already installed. :/

Mac App Store Notes: Recognizing Previously-Installed Apps, Pricing Discounts

Applications installed outside the Mac App Store: The Mac App Store automatically recognizes when a user already has Apple apps such as iLife '11 and iWork '09 installed on his or her system, showing an "installed" note in place of the purchase button in the store. The same does not appear to be true for third-party applications, however, as our previously-installed copy of TextWrangler was not picked up by the Mac App Store.

I think the OP is asking if there is a list of all the apps that the store already knows about, instead of you going to each app's page and seeing if it shows as Installed or not.

And FWIW, third-party apps are showing up for me as installed, such as Coda and Transmit.
