If you take a closer look at the MOApp website
you will see that my English - well - to be honest: it sucks :-)
So Dictionary.app is one of my most used apps. Unfortunately it terminates itself when closed and you always have to reopen it again. So I wrote this little tool to open Dictionary by shortcut or menu bar and maybe it can be useful for others, too...
If you want you can add launchDictionary to your startup items (System Preferences > Accounts > Login Items)
