YAOXILONG thank you for the update, just installed and the changes are pleasing.
EQ, High/Low pass filters update is a great step, as well as fixing a but that deletes manual distance entries in surround settings when changing from "Independent" to "Linkage" and then back to "Independent".
Two PiP mode is much better addition, as it allows any size window instead of fixed sizes in minimalist mode.
If your team can bring an update that allows to change default Bluetooth name from DUDUAUTO to any other would make this even better. Also, volume change to logarithmic would be a wise decision at this stage if haven't implemented yet.
