Split windows in windows 10

Expresii doesn't seem to work with split windows. I would find it useful to have for example a You Tube demo running alongside Expresii so that I can work alongside the video. Is that possible?

Thanks for your message. I'm aware of the issue, but am not sure why Expresii's window is not listed as the second window candidate. I'll see what I can do to fix this. It is not possible to initiate snapping via dragging of the title bar, because the UI framework I use seems to be not supporting that. Again, I'll see if the author of the framework can fix this.

Please try Expresii Version 2021.01.25. It now can at least appear in the second window list - so you would need to drag your other app e.g. Youtube to one side, and then select Expresii in the window list as the second window. Note that once you toggle Fullscreen mode in Expresii, it won't appear in the list any more. This is the best I can do for now.
