Great solution for remote control of a laptop
Response from developer
Thank you, ekrub. You asked for the right thing, and it is in 1.2.1. The key (password) button is gone from the control bar unless you ask for it. It is off by default, and you turn it on for one Mac at a time with a switch in that Mac's settings, which you reach from the info button (ⓘ) at the end of its row in the list. On a fresh install, and on every Mac you never opt in to, there is simply no button there to mistap. We also added a guard for the exact accident you described, because we ran into it ourselves while testing. When the picture on your screen has fallen behind the Mac, Headroom now says so in a banner, and the key button waits eight seconds instead of two and a half before it can be tapped again. The bad version of this is sending the password once, seeing nothing change because the picture is stale, and sending it again into whatever has focus by then. 1.2.1 also fixes what made the picture fall behind. When the whole remote screen kept changing, our request for the next frame reached the Mac while it was still writing the previous one, and was dropped — so nothing arrived until a ten-second keep-alive woke it up. That is fixed, and frames keep coming now. I would rather be straight with you about what is not fixed. On a login screen that animates its own background, typed characters still take a couple of seconds to appear. The cause is on the Mac's side of the screen sharing protocol and we have not found a way around it yet. That is exactly why the banner and the longer wait exist: the accident you imagined is still possible, so the app warns you rather than pretending. The Mac version has the same changes. Thank you for writing it up so clearly. This change happened because you did.
