I agree that it could use some tweaking: It would be nice to put a red dot or something for an application not yet installed.
Regarding the "Export" request, a temporary work-around (though far from elegant, I admit) is to just Save your session and look at the .db file in your ~/Library/Application Support/AppShelf directory. It is (mostly) human-readable.
My Delicious Library 2 from importing the auto-generated MH license file worked just fine.
Also, the upgrade to version 1.3 seemed to proceed without a hitch, although I made doubly-sure that I had svaed the database before doing the upgrade. Maybe that is another glitch in the program...that it should save changes before doing an automatic upgrade or quitting.
Anyway, I have no complaints about this FREE bonus.
