Thank you for your voices. I have mentioned your use cases to the product management team. However, since we have a big focus on PC gaming at the moment due to our collaboration with SteelSeries, there are many other things that are more important than multi-monitor support. (since most games just use one screen)
If/when we switch focus to a more general desktop solution, this priority might change. But at the moment, we are not working on multi-monitor support actively.
