I always liked their original UI - Photon[1][2]. Very lightweight and fast. Also a distinct and consistent style. I understand why they dropped it in favor of Qt and later Web technologies, but it's still a big loss. [1] https://www.qnx.com/developers/docs/6.5.0SP1.update/com.qnx....

The arrows of time branch and spiral, so it's possible that "later" could require some properties of "earlier".
If Photon could not be open-sourced, it could be licensed to a third party for custodian maintenance. If QNX is abandoning Photon forever, would Blackberry object to Photon being cloned for Linux or FreeBSD? That could preserve a future option for QNX to use it again, like XFCE.
