One thing that I see glossed over on the engineering side is reactive UI that changes as the models its built from change. This is good for many things except when it comes to presenting the user with UI objects they need to interact with. It has to be one of the dumbest and most infuriating things in UX and is often seen as working as intended. If you present something to the user do not change the options right before they click. If you aren’t ready to show any options, don’t!
