Some of you guys cannot be serious. I’ve been REALLY using (and teaching other professionals to use) (almost) every notation program there is and has been for about 30 years. Dorico is (and will be) much much better than anything we have seen. Not perfect, perhaps, but still BY FAR the best.
What do you want with your complaining and dreaming? Do you want to SUPPORT and THANK these GREAT guys who are working very hard to give us what most of us want, or do you “just” want them to create a new notation program individually for each of you? A custom-built notation program made ONLY for YOU? Perhaps even a new program for every PROJECT of yours? 
You should do your work yourself instead of asking others to do it for you, so dream on.
You guys, really, should think before you… 
The OP’s title “What’s wrong in the world of notation software?” itself is wrong. It should be “What’s wrong in the world of notation software users/complainers?” The answer is above.
