I have just release the latest build v1.20.14 which is a cosmetic build, no new features, but it consolidates the Designer build, with the End user build.
This means that you no longer need to switch between plugin builds, in order to receive the Designer Build benefits - mainly Gauges Widget. All you need to do is just open the "Options Widget" and tick the
" ** Designer Mode ** " option, and the next time you open the "Gauges Widget" it will have the "Designer Build" looks.
Another important behavior you receive is the <Developer ...> element which will take effect once you start the mission.
The second news is that the Fifth tutorial, the Sound tutorial for v1.20 is out. It is a short one with a downloaded demo.
Hope it will help.
Cheers
