The new version 1.2 is now undergoing the certification at WP store, so it will be out within a couple of days.
There is a lot of changes and new features such as trackable items management (Full changelog).
The good thing is that it works fully offline, so logs are waiting until the internet connection is restored. Just check the icon on the start page. The new page now displays list of logs waiting in the queue for the upload and a list of errors. The errors may occur when you submit wrong tracking code of the item.
Another big thing is that everybody will be able to try the new version for 20 day regardless of previously expired trials.
