A little feedback:

The package is placed in Section: user/games. user/office would be more appropriate

What's your view on localization? Some elements obey the device language setting, but most elements are English. Any plans for adding translation files like in OMP?

And finally: will you publish the source code any time soon? I am interested see how you implemented some parts of the date picker.

Edit: P.s. I see you are trying to upload to extra devel. I can always get the source there once that succeeds.
