CTO & CoFounder of CoScreen here. Thanks for your feedback, we will definitely make it more prominent that single monitor use is definitely a viable use case. The best experience is definitely with a secondary monitor, that was the original conception of the product, but we have a model of tab-based sharing, and a mechanism to hide windows of specific users, as well as focus the windows of a specific user (click their profile picture), that have made interacting with it on a single monitor a lot more intuitive and nice. Many of our developers use it exclusively with a single monitor.
