It's happening to me to. Really annoying. I may have to write an AutoHotKey script to minimize the window after some amount of inactivity.

If anyone else find their way here, here is an AutoHotKey script that will minimize Opera and turn off the monitor. During development of the script, I bound a key to just turn off the monitor. With Opera not-minimized, when I would hit the key, the monitor would turn off, and then turn back on in less than a second. With Opera minimized, it would turn off and stay off.

Note that if you have sound playing through the browser when this script triggers, the sound will continue. That's a good thing since many people will be using the browser for music, or other background noise.

Just put this at the top of your bind-key script. Don't bind it to any key. It will not block the script from reading the rest of your keys.

Loop {
  if (A_TimeIdle > 120000) {
    if WinExist("ahk_exe opera.exe") {
      WinMinimize
      Sleep, 500
      SendMessage 0x112, 0xF170, 2, , Program Manager
    }
  }
  Sleep, 10000
}

Multi-range looper isn't working for me. I just get the usual YouTube right-click menu when I right-click on the timeline. It would be a nice feature since I like to watch roller skate technique videos and I'l like to be able to set up a loop to figure out moves. Otherwise, this is a really nice add-on. 4 stars for now, 5 when looper is working. Thanks!
