Didn't notice anything else, I was mainly waiting for a responsiveness fix updates haha I guess first updates will be bug fixes focused, but never encountered any except lag/responsiveness so happy with that
Latest 1.0.4.0 update for Mi 12 Lite (Taoyao) resolved all lag/responsiveness issues I had with the first HyperOS version 1.0.2.0 ! Now it's finally better than MIUI !
