I make this for myself and share it with others. Take it or leave it.
Yes, it has seen a rash of regressions because the features are designed to interact with each other. But, it is getting better with each new version since 18.05. The next version 18.08 due August 1 will contain only fixes. All the others in this thread are not developers. Only I am and someone else occasionally. I have not been shrugging it off but instead busily working on the fixes.
The points have been made, I will not remove Shotcut from public consumption, and I will continue onward as I always have. There have always been people complaining and others praising. That is the way of the world. There have been other times in the past 6 years when there have been periods of instability before reaching the stability that version that 18.03 offers. I am fairly confident I can bring it back to that level in the next couple of months. It is very unfortunate that there have been so few bug fixes submitted the open source way.
