Applying the perform mode's effects permanently

happy to say, I sold my device mainly because this feature was ignored, as well as many other wishes that have many votes for that seem to do nothing after all. the most significant bummer is heavily related and was posted before I started this thread as a compromise:

with these two things implemented (this thread + the one above) it would be an instant buy, even if the newer Play+ that seems to have a lot of bugs and still misses a lot of features, whatever.
