I honestly don’t have additional insight. Our small team only has so much development time in a week and it often goes to more pressing issues such as bugs or otherwise. When there’s time available, I do know the team has been working on it. A while back a screenshot was even shared with some progress.
The thing is that SignalRGB is a more complicated application than it may seem and we want to get it right. Sorry I can’t tell you when Elder Scrolls 6 will release either (but I wish I knew that too).
