Easy way to check app version?

Is there an easy way to check the app version? I noticed it is sometimes hard to tell if I already put the latest version in my application or not. The way I do it now is to check the filedate of the .mpk but there should be a better way I think. Only the community commons app has a clear version number in the module (empty directory with the version name). Where is the version number stored within the .mpk? Should all apps contain the empty directory with the version number? I like this very much because know I can see within my application if I should upgrade or not. But then again this would only apply for the modules. Should the version number be in the name of all the standalone apps? I like to hear what would be the best practise. Regards, Ronald
