The process priority manager already has a concept of "perceivable tabs" (i.e. ones that are playing some form of audio) and assigns them a higher priority compared to non-playing background ones. Unfortunately the Windows-specific mapping of those priorities lumps them together because Windows has only one background scheduling class. However if we run into problems like skipping or jittering audio it will be trivial to put them back in the normal priority class. Gabriele
