I just copied a .sh script to my desktop and clicked on it. It launched the application. However the right click and make new shortcut has been removed. Was it a feature , yes. Should they have kept it, I say no You can't keep every menu option ever in all your dialogs. There are other ways ( and better ways ) to do the same thing.
What are those other and better ways? The ability to bind random, personalized, easy to create scripts to file actions has been removed as far as I can tell.
Not being able to drop a shell script into some place to make GUI file management easier is a regression. (I say "some place" because when I was using this feature, it took forever to find the right place as it changed between released/distributions and I had to experiment to find the right set of env vars that are set, because docs were lacking).
