Yes, exactly this one. It sometimes doesn't work well enough on my LG 5K2K, but most of the time I'm happy with it. Even assigned separate shortcuts (CTRL+F1/F2) for the laptop display, very practical to quickly dim it when watching something dark on the big monitor.
Little worried about privacy with 3rd party apps like these
It being an open source project with the code actually in GitHub I don't think there would be any issue, but you never know, and the binaries might not be clean/untouched... You could compile it yourself from the source but I don't bother.
