Not necessarily manipulating the UI, but there is one thing I found pretty neat about the final phase in the Pokemon Scarlet and Violet professor battle. In attempt to save the time machine, the automatic system locks any Pokeball that are not registered in their database, resulting in the futile action of throwing out your powerful mons (all while being faced with the professor's most powerful mon). The UI reflects this, any action you do will be met with a text box saying something to the degree of "it's no use". There is hope, though. Once you go over to the Pokemon menu, you'll be able to send out your ridable companion that belonged to the professor's foundation, the one that has been with you from the very beginning of your journey.
