New versions of the application have been uploaded to the first post in this thread. Support for password-protected ZIP and RAR files was added. The current image can now be saved via a menu item. The directory it is saved to is configurable. The step size is also configurable now, to help 611 users who don't have a Back button for taking smaller steps. The configuration was also fixed to work on the 611. All these changes are thanks to Klapo.
Added French and Portuguese translations from Pascal V., and a German translation from seiichiro018.
