5) When the counter reaches 0, Kstars indicates that a meridian flip is in progress. However Onstep doesn't move (the App does indicate the "Goto" icon though).

This will not work.
You need to set OnStep so that it will trigger a flip at the same time that KStars will. That is, they are synchronized.

What you did should work if you set KStars to, say 0.5hr, and OnStep to 7.5 degrees.
