About the MuseScore 3 features not implemented in MuseScore 4

Will these features be added in MuseScore 4 again? Or some will just disappear?
For example, the scores I made before can be well played in MuseScore 3, but when I use MuseScore 4 to play it, the sound seems terrible, because the function of tuning individual notes in MuseScore 3 doesn't work in MuseScore 4.
I hope at least this function will be keep.
这些功能还会再次被添加到musescore4中吗？或者有一些就永久性消失了？
比如单个音符的调控这个功能，我之前做的乐谱，放在musescore3里能播放的比较好听，但放在musescore4里就因为没有了这个功能，乐谱播放时达不到musescore3的效果。
