I just thought of and implemented a new feature - a pilot log! Every arrested landing is logged to a text file, and a log viewer can be accessed by an entry in the Add-Ons menu.
In terms of a release time, no more features are to be added, just tweaks to the current code and a lot of testing to make sure it works - and I am yet to see it fail. It has turned out to be very robust, I can't break it, I've even tried doing a catapult launch over a wire with the hook down! I'm expecting testing to go smoothly before introducing a wider beta test and eventually a general release.
