A great little app indeed
These days, with an explosion of so many good apps on the app store, it has become difficult to keep so many icons of useful apps on the dock, without reducing its size and thus usability. It is therefore a wonderful idea to keep apps like address book (which you dont need to open fully every time) to keep on the task bar. I think dictionary should also be on the task bar.
