Issue #7 is that Play/Pause get "hijacked" by Safari tabs if it starts playing audio (music / video / notification). For example if I have music playing in iTunes and then visit a YouTube page. Normally I'd press Play/Pause and iTunes paused. However now Safari hijacks the media keys and pressing Play/Pause pauses the video. Now I have to switch to iTunes and CLICK the play/pause button, and then switch back to the Youtube video. Even worse: this happens with websites playing audio notifications (e.g. WhatsApp Web). When this happens, Play/Pause stay mapped to that website's notification sound and I have to close the tab before the key is released back to iTunes.
