i use an ios chinese dictionary called pleco that, for some reason, the developers don’t allow to be installed on macos. i primarly use my macbook to study, and before this update, i just checked definitions using the app on my phone. now, i have my ipad directly next to my macbook on a stand, and i can easily drag the mouse across and and look up entries without needing to unlock my phone and peck out or copy/paste characters. these kind of small optimizations to workflow are really helpful.
