Around the input of independent voice there seem to be some focus issues.
It starts when you activate independent playback. Instead of staying at the instrument you just activated the focus jumps to the top of the top of player list. So you have to scroll back to the player/instrument . This is reproducible. Also when you enter a new channel for an instrument in one of the voices and press enter the focus often but not always jumps back to the top of the instrument list. Annoying if you have multiple cello voices and want to enter one after the other. Each time you have to scroll back from piccolo to cello nearly at the bottom of the list.
Another undesired behaviour is that when activating independent playback often a new instance is created in the VST and Midi bank and even linked with the voice. So e.g. if you use VEP you get a non connected copy of the original bank entry for the first voice. Probably well thought if you use separate plugins but annoying if you use VEP. I did not find anything in the setting to deactivate this behaviour.
