yes, thank you, I meanwhile remembered during the day there is extended desktop, I just did not use lineage for quite a time and for some reason thought it is something else. I tried global ON for it but then I had problems waking up the phone, i would hear the unlock sound, but display was off, it took like 30 seconds and several attempts to wake the phone. as soon as I set the global switch off, and just set the rules per app, which anyway is better, in some app I want both hidden, in some only status bar, it works great.
Today I had a lot of phone calls, listened to spotify, even watched couple sitcom episodes in the morning, and battery life is still great, if that percentage can be trusted. Funny enough VLC took 6% for more than an hour of video playback, Spotify for the same amount 11%.
That audiofx would be worth a try.
Great rom, really, for a long time I was not so excited.
